Ever-developing energy storage technologies demand the pursuit of advanced materials with multiple functionalities. Recent studies revealed that multiple heteroatom-doped carbon has been wildly used for bi-functional or even tri-functional energy storage and conversion. However, few efforts have been made to uncover the origin of multi-functionalities. Herein, a nitrogen, phosphorus, and sulfur tri-doped carbon is designed in this work with large porosity, rich heteroatoms doping and high mass density, exhibiting excellent bifunctionalities on supercapacitors and oxygen reduction reaction. Importantly, the density functional theory calculations demonstrate the relevant co-doping and tri-doping generate more active sites on neighboring carbon atoms than single doping, and the same type of active sites may enhance bifunctionalities simultaneously. The present investigations provide a promising guidance on the design of multi-functional materials for future energy storage and conversion applications. 相似文献

As byproducts of the meat‐processing industry, nearly 100 million tons of bones, skin, and scales are generated from livestock, poultry, and fish every year and are generally discarded as waste. However, these widespread and low‐cost biomass materials are rich in collagen that is primarily composed of the elements C, N, O, and S. By controlled pyrolysis, these collagen‐enriched biomass materials can be transformed into biomass‐derived porous carbons (BPCs). The ordered biotic structures and specific elemental compositions of the natural precursors endow BPCs with unique nanostructures and heteroatom doping, leading to promising applications in electrochemical energy storage and conversion. In particular, BPCs derived from animal bones and fish scales show novel porosities and morphologies due to their abundance of hydroxyapatite crystals, which act as naturally occurring nanostructured templates. Here, the first review focusing on the design and synthesis of collagen‐derived porous carbons (CPCs) is given. The specific applications of different CPCs in electrochemical energy storage and conversion are also summarized. Finally, the challenges and prospects for the controllable synthesis and large‐scale applications of CPCs are assessed. 相似文献

High porosity combined with mechanical durability in conductive materials is in high demand for special applications in energy storage under limiting conditions, and it is fundamentally important for establishing a relationship between the structure/chemistry of these materials and their properties. Herein, polymer‐assisted self‐assembly and cross‐linking are combined for reduced graphene oxide (rGO)‐based aerogels with reversible compressibility, high elasticity, and extreme durability. The strong interplay of cross‐linked rGO (x‐rGO) aerogels results in high porosity and low density due to the re‐stacking inhibition and steric hinderance of the polymer chains, yet it makes mechanical durability and structural bicontinuity possible even under compressive strains because of the coupling of directional x‐rGO networks with polymer viscoelasticity. The x‐rGO aerogels retain >140% and >1400% increases in the gravimetric and volumetric capacitances, respectively, at 90% compressive strain, showing reversible change and stability of the volumetric capacitance under both static and dynamic compressions; this makes them applicable to energy storage devices whose volume and mass must be limited. 相似文献

The modification of microporous carbon foam with boron and nitrogen through a facile microwave chemical treatment are reported. The resulting surfaces of the foam exhibit distinct B–N and carbon domains based on chemical and microscopic analysis, in keeping with theoretical predictions. The resultant materials are shown to exhibit exceptionally high methanol desorption enthalpy and thermal stability in comparison to untreated carbon foam and consequently are suggested as candidate materials for sorption cooling and thermal storage applications using methanol as the adsorbate. 相似文献

Thermal energy storage technologies based on phase‐change materials (PCMs) have received tremendous attention in recent years. These materials are capable of reversibly storing large amounts of thermal energy during the isothermal phase transition and offer enormous potential in the development of state‐of‐the‐art renewable energy infrastructure. Thermal conductivity plays a vital role in regulating the thermal charging and discharging rate of PCMs and improving the heat‐utilization efficiency. The strategies for tuning the thermal conductivity of PCMs and their potential energy applications, such as thermal energy harvesting and storage, thermal management of batteries, thermal diodes, and other forms of energy utilization, are summarized systematically. Furthermore, a research perspective is given to highlight emerging research directions of engineering advanced functional PCMs for energy applications. 相似文献

Multivariate metal–organic frameworks (MTV-MOFs) provide a handle over programming MOF's physicochemical properties for use in functional applications. In this review, the state-of-art design features of MTV-MOFs are summarized, including multivariate functionalities, mixed metals, and post-synthetic modification, and highlight their resulting fine-tuned performance in practical applications, such as gas storage, gas separation, water harvesting, luminescence sensing, heterogeneous catalysis, and drug delivery. Furthermore, a vision is provided for future research avenues, in which MTV-MOFs enable the incorporation of a variety of functionalities, metals, linkers, secondary building units (SBUs), and pore metrics along a specific crystallographic direction with respect to the ordered backbone. Future directions focus on mechanistic and kinetics investigations into the formation of MTV-MOFs in addition to high-throughput screening with the aim of automation and artificial intelligence. 相似文献

As a chemical product with rapidly expanding demand in the field of modern energy and environmental applications, hydrogen peroxide (H2O2) has garnered widespread attention. However, the existing industrial production of H2O2 is plagued by high energy consumption, harmful waste emission, and severe safety issues, making it difficult to satisfy the environmental/economic production concept. Artificial photosynthesis offers a viable strategy for green and sustainable H2O2 production since it uses sunlight as an energy source to initiate the reaction of oxygen and water to produce H2O2. Among various photocatalysts, covalent organic frameworks (COFs), featuring highly ordered skeletons and well-defined active sites, have emerged as promising photocatalysts for H2O2 production. This review presents the nascent and burgeoning area of photocatalytic H2O2 production based on COFs. First, a brief overview of photocatalytic technology is provided, followed by a detailed introduction to the principles and evaluation of the photocatalytic H2O2 generation. Subsequently, the latest research progress on the judicious design of COFs for H2O2 photosynthesis is expounded, with a particular emphasis on manipulating the electronic structures and redox active sites. Finally, an outlook on the challenges and future opportunities is proposed, in the hope of stimulating further explorations of novel molecular-designed COFs for sustainable photosynthesis. 相似文献

Material and energy efficiencies are two key parameters that benchmark the electrochemical energy conversion and storage devices (EECSDs). Maximizing both requires researchers to grasp the limits of the physiochemical properties of core electrode materials. Ordered mesoporous materials (OMMs) have been regarded as promising electrode materials; however, their intrinsic deficiencies (e.g., plugs, inaccessible pores, and surfaces) impose limits for wide applications. 2D ordered mesoporous materials (2DOMMs) featured with an extended lateral dimension and a nanometer thickness not only inherit the structure advantages of mesoporous materials, but also have a unique 2D ultrathin feature that can fully address the imperfections of conventional OMMs. Herein, recent achievements on the preparation of 2DOMMs by combining single micelle assembly strategy with 2D bottom-up patterning techniques including the molecular/space confined, interfacial orientated, and surface limited assembly are focused. Special focus is devoted to the newly developed synthetic strategies and their fundamental mechanisms for accurate control of some key structural parameters. Recent advances of 2DOMMs in EECSDs are also highlighted, which suggest that 2DOMMs are excellent material platforms for developing new battery chemistry as well as targeting performance optimization and cost reduction. Finally, the challenges and prospects are proposed based on current development. 相似文献

Hydrogen has attracted a great share of attention both as an energy carrier and as an irreplaceble reagent for many industrial processes. Photoactivated routes, ranging from photocatalytic and photo‐electrochemical water splitting to photoreforming of suitable oxygenates, appear to be attractive long‐term solutions among possible strategies for hydrogen production. However, the success of such processes depends on the efficient use of solar energy and on the identification of active and stable catalysts, which, in addition, should be eco‐friendly and available in large amounts at accessible costs. Researchers are exploring the use of supported oxide nanomaterials, which enable an easy catalyst recovery and exhibit unique advantages due to their peculiar nano‐organization. In this Feature Article, the potential of such systems towards photoinduced hydrogen evolution is discussed based on selected case studies that highlight the relations between structure, morphology, composition, and functional performances of oxide nanomaterials. In addition, potential limitations of oxide‐based nanomaterials as well as unexplored key aspects that require special attention in future investigations are discussed. 相似文献

Porous carbon materials have demonstrated exceptional performance in a variety of energy‐ and environment‐related applications. Over the past decades, tremendous efforts have been made in the coordinated design and fabrication of porous carbon nanoarchitectures in terms of pore sizes, surface chemistry, and structure. Herein, structure‐oriented carbon design and applications are reviewed. The unique properties of porous carbon materials that offer them promising design opportunities and broad applicability in some representative fields, including water remediation, CO2 capture, lithium‐ion batteries, lithium–sulfur batteries, lithium metal anodes, Na‐ion batteries, K‐ion batteries, supercapacitors, and the oxygen reduction reaction are highlighted. Then, the most up‐to‐date strategies for structural control and functionalization of porous carbons are summarized, toward tailoring microporous, mesoporous, macroporous, and hierarchically porous carbons with disordered or ordered, amorphous or graphitic structures. Meanwhile, the emerging features of these structures in various applications are introduced where applicable. Finally, insights into the challenges and perspectives for future development are provided. 相似文献

Structural energy storage materials refer to a broad category of multifunctional materials which can simultaneously provide load bearing and energy storage to achieve weight reduction in weight‐sensitive applications. Reliable and satisfactory performance in each function, load bearing or energy storage, requires peculiar material design with potential trade‐offs between them. Here, the trade‐offs between functionalities in an emerging class of nanomaterials, carbon nanofibers (CNFs), are unraveled. The CNFs are fabricated by emulsion and coaxial electrospinning and activated by KOH at different activation conditions. The effect of activation on supercapacitor performance is analyzed using two electrode test cells with aqueous electrolyte. Porous CNFs show promising energy storage capacity (191.3 F g?1 and excellent cyclic stability) and load‐bearing capability (σf > 0.55 ± 0.15 GPa and E > 27.4 ± 2.6 GPa). While activation enhances surface area and capacitance, it introduces flaws in the material, such as nanopores, reducing mechanical properties. It is found that moderate activation can lead to dramatic improvement in capacitance (by >300%), at a rather moderate loss in strength (<17%). The gain in specific surface area and capacitance in CNFs is many times those observed in bulk carbon structures, such as carbon fibers, indicating that activation is mainly effective near the free surfaces and for low‐dimensional materials. 相似文献

The visible‐light‐driven photocatalytic CO2 reduction is one appealing approach to simultaneously mitigate the energy crisis and environmental issues. It is highly desirable but challenging to selectively and efficiently convert CO2 into desirable products. Herein, a covalent organic framework hosting metalloporphyrin‐based carbon dots (M‐PCD@TD‐COF, M = Ni, Co, and Fe) is first presented, which serves as heterogeneous catalysts for CO2 photoreduction. M‐PCD@TD‐COF not only enriches available COF‐based catalytic materials, but also provides suitable environment for CO2 adsorption and activation on metalloporphyrin‐based carbon dots. The advantages of the host environment in COFs are highlighted by the satisfactory catalytic activity and remarkable selectivity of CO2‐to‐CO conversion over H2 generation up to 98%. The photocatalytic system is effective for both pure CO2 and the simulated flue gas. This work provides new protocols for the rational design of COF‐based heterogeneous catalysts for selective CO2 photoreduction. 相似文献

The design and fabrication of solar‐to‐chemical energy conversion devices are enabled through interweaving multiple components with various morphologies and unique functions using a versatile layer‐by‐layer assembly method. Cationic and anionic polyelectrolytes are used as an electrostatic adhesive to assemble the following functional materials: plasmonic Ag nanoparticles for improved light harvesting, upconversion nanoparticles for utilization of near‐infrared light, and polyoxometalate water oxidation catalysts for enhanced catalytic activity. Polyelectrolytes also have an additional function of passivating the surface recombination centers of the underlying photoelectrode. These functional components are precisely assembled on a model photoanode (e.g., Fe2O3 and BiVO4) in a desired order and various combinations without degradation of their intrinsic properties. As a result, the performance of water oxidation photoanodes is synergistically enhanced. This study can enable the design and fabrication of novel solar‐to‐chemical energy conversion devices. 相似文献

Nano‐ and mesoporous boron carbon nitrides with very high surface areas up to 1560 m2 g?1 are obtained by pyrolysis of a graphitic carbon nitride mpg‐C3N4 infiltrated with a borane complex. This reactive hard‐templating approach provides easy composition and texture tuning by temperature adjustment between 800 and 1400 °C. The process yields BxCyNzOvHw materials as direct copies of the initial template with controlled compositions of 0.15 ≤ x ≤ 0.36, 0.10 ≤ y ≤ 0.12, 0.14 ≤ z ≤ 0.32, and 0.11 ≤ v ≤ 0.28. The nano and mesoporosities can also be tuned in order to provide hierarchical materials with specific surface areas ranging from 610 to 1560 m2 g?1. Such high values, coupled with resistance against air oxidation up to 700 °C, suggest potential materials for gas storage and as catalyst supports. Indeed, it is demonstrated that these compounds exhibit high and tunable H2 uptakes from 0.55 to 1.07 wt.% at 77 K and 1 bar, thus guiding further search of materials for hydrogen storage. 相似文献

Metal-organic frameworks (MOFs) with orderly porous structure, large surface area, high electrochemical response and chemical tunability have been widely studied for energy conversion and storage. However, most reported MOFs still suffer from poor stability, insufficient conductivity, and low utilization of active sites. One strategy to circumvent these issues is to optimize MOFs via designing composites. Here, the design principle from the viewpoint of the intrinsic relationships among various components will be illuminated to acquire the synergistic effects, including two working modes: (1) MOFs with assistant components, (2) MOFs with other function components. This review introduces recent research progress of MOF-based composites with their typical applications in energy conversion (catalysis) and storage (supercapacitor and ion battery). Finally, the challenges and future prospects of MOF-based composites will be discussed in terms of maximizing composite properties. 相似文献
