The development of trifunctional electrocatalyst for oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and hydrogen evolution reaction (HER) with deeply understanding the mechanism to enhance the electrochemical performance is still a challenging task. In this work, the distorted metastable hybrid-phase induced 1T′/1T Co,P SnS2 nanosheets on carbon cloth (1T′/1T Co,P SnS2@CC) is prepared and examined. The density functional theoretical (DFT) calculation suggests that the distorted 1T′/1T Co,P SnS2 can provide excellent conductivity and strong hydrogen adsorption ability. The electronic structure tuning and enhancement mechanism of electrochemical performance are investigated and discussed. The optimal 1T′/1T Co,P SnS2@CC catalyst exhibits low overpotential of ≈94 and 219.7 mV at 10 mA cm−2 for HER and OER, respectively. Remarkably, the catalyst exhibits exceptional ORR activity with small onset potential value (≈0.94 V) and half-wave potential (≈0.87 V). Most significantly, the 1T′/1T Co,P SnS2||Co,P SnS2 electrolyzer required small cell voltages of ≈1.53, 1.70, and 1.82 V at 10, 100, and 400 mA cm−2, respectively, which are better than those of state-of-the-art Pt-C||RuO2 (≈1.56 and 1.84 V at 10 and 100 mA cm−2). The present study suggests a new approach for the preparation of large-scalable, high performance hierarchical 3D next-generation trifunctional electrocatalysts. 相似文献

Amphiphilic biosynthetic hydrogels comprising natural polysaccharide alginate (I) and synthetic polyester polypropylene fumarate (II) units were prepared by crosslinking the copolymer of I and II with calcium ion and vinyl monomers viz, 2-hydroxyethyl methacrylate (HEMA), methyl methacrylate (MMA), butyl methacrylate (BMA) and N,N′-methylene bisacrylamide (NMBA). Three fast degradable hydrogels, ALPF-MMA, ALPF-HEMA and ALPF-BMA and one slow degradable hydrogel ALPF-NMBA were prepared. These hydrogels are amphiphilic and able to hold sufficient amount of proteins on their surfaces. All these hydrogels are found to be hemocompatible, cytocompatible and genocompatible. ALPF-NMBA promotes infiltration of L929 fibroblasts and 3D growth of H9c2 cardiomyoblasts and long-term viability. 相似文献

Electrical conductivity is emerging as one of the most essential material's qualities of the 21st century due to the lightning-fast advancements in the electronics sector and the continuously improving electrical goods. As conductive materials are used in the majority of the modern items we use, including power sources, energy generating systems, electrical circuits, sensors, and many others, continuing advancement in this field is very crucial. The novelty of this work lies in the dispersion of ferrite nanoparticles, which was synthesized using egg albumen to enhance the electrical behavior of PANI polymer films. In this research work, a simple casting approach was used to ex situ polymerize aniline to fabricate ultrathin and flexible CuFe2O4 distributed PANI films for electrical conductivity applications. The combustion approach was used to produce the copper ferrite nanoparticles, while egg albumen was not only used as the fuel but also it was used a capping agent to control the size of ferrite NPs with a size much lower than that already reported. Studies on the structural, morphological, and electrical properties of pure and various weight percent of (1 , 3 , and 5 wt%) CuFe2O4 loaded PANI films were performed. Comparing the different films, the 5 wt% CuFe2O4 dispersed PANI films exhibited remarkable and greatly improved permittivity and electrical conductivity with low dielectric loss. This indicates the 5 wt% CuFe2O4 dispersed PANI films have the prospective uses in high-tech industries where there is a need for flexible, thin, and lightweight high electrical conducting materials with lesser loss factor. 相似文献
