LiNO3-NaNO3-KNO3三元熔盐材料的设计及热稳定性研究

采用共形离子溶液模型(conformalionic solution model, CIS) 在二元熔盐体系相图的基础上，对三元熔盐体系LiNO₃-NaNO₃-KNO₃进行了相图计算，得到该三元体系最低共熔点为117.7℃，相应的摩尔分数组成分别为x(LiNO₃) = 0.375，x(NaNO₃) = 0.075，x(KNO₃) = 0.550。按照热力学最低共熔点计算结果，采用熔融法制备了三元硝酸熔盐，通过DSC和TG实验测定其最低共熔点为118.3℃，这与计算得到的结果(117.7℃)基本一致。TG测试结果表明当温度低于587.2℃时，该三元熔盐体系较为稳定，其工作温度范围为118.3~587.2℃，该三元硝酸熔盐适合在太阳能热发电中作为高温传热蓄热材料使用。     

Solar Photocatalytic Degradation of Textile Dyes in TiO2 Suspended Solutions

The degradation and decolourization of direct dye (Everdirect supra turguoise blue, FBL), acidic dye (Isolan orange S-RL) and vat dye (Indanthren red FBB) have been investigated by solar/TiO2 process. The effects of solution pH, dye concentration, dosage of TiO2 and nano-size of TiO2 have been studied. The increase in initial pH (3, 5 and 11) and dye concentration decrease the removal rate. The treatment for FBB and FBL dye solutions is more efficient than that of S-RL.Under optimum conditions, the color removal is found to be almost complete for FBB and FBL while that of S-RL also reaches 95%. Langmuir adsorption isotherm and modified Langmuir-Hinshelwood kinetic model (L-H model) have been fitted to the experimental data and found to correlate the adsorption patterns as well as the kinetics of the dyes studied.

A novel high-performance counter electrode for dye-sensitized solar cells

A novel Pt counter electrode for dye-sensitized solar cells (DSC) was prepared by thermal decomposition of H₂PtCl₆ on NiP-plated glass substrate. The charge-transfer kinetic properties of the platinized NiP-plated glass electrode (Pt/NiP electrode) for triiodide reduction were studied by electrochemical impedance spectroscopy. Pt/NiP electrode has the advantage over the platinized FTO conducting glass electrode (Pt/FTO electrode) in increasing the light reflectance and reducing the sheet resistance leading to improve the light harvest efficiency and the fill factor of the dye-sensitized solar cells effectively. The photon-to-current efficiency and the overall conversion efficiency of DSC using Pt/NiP counter electrode is increased by 20% and 33%, respectively, compared to that of using Pt/FTO counter electrode. Examination of the anodic dissolution and the long-term test on the variation of charge-transfer resistance indicates the good stability of the Pt/NiP electrode in the electrolyte containing iodide/triiodide.

Addressing the CO2 dilemma

Perspectives are offered for reducing the impact of huge amounts of CO₂ produced today from power generation and transportation vehicles. The origins of the dilemma between the world’s increasing use of hydrocarbons as an energy source and the cogeneration of CO₂ which results as a co-product are discussed. Hydrocarbons will provide much of the fuel needs for these major, global industries for the next 20 years and meet 60% of the world’s energy demand. With the growth of both power generation and transportation vehicles around the world, CO₂ levels will continue to increase in the atmosphere. Renewables such as wind, dams, and biomass will not be able to handle all the energy demand. Technology breakthroughs are needed to reduce the world’s dependence on fossil fuels, which will be aggravated by the drive to use more coal. Current approaches for removing CO₂ are discussed as well as near term and future options with particular focus on how catalysis can offer some solutions. In particular, solar photocatalysis based approaches offer a potentially viable energy solution.
