中文摘要:
      金属有机框架材料(MOFs)是由金属原子或原子团簇与有机配体构成的多孔材料,具有良好的吸附性和光催化活性。基于对植物光合作用的模拟,MOFs材料光催化将CO2还原转化为系列碳氢化合物燃料在环境保护和未来能源供应方面具有广阔的应用前景。本文简述了MOFs光催化还原CO2的机理,通过对催化剂进行设计,如:能带结构工程(掺杂、配体取代、构建异质结等),形貌结构功能化以及协同催化等方式,实现材料的较强光捕获、较高的气体吸附量、产物选择性、稳定性和光催化效率。并提出了光催化还原CO2的发展趋势。
英文摘要:
      Metal-organic frameworks (MOFs), the preferred porous materials,consisting of metal atoms or clusters and organic ligands, showing the higher adsorbability and photocatalytic activity, have been widely exploited in environmental protection and future energy supply. Based on the simulation of plant photosynthesis, MOFs is expected to convert CO2 into a series of hydrocarbon fuels. This article illustrated the mechanism of MOFs photocatalytic reduction CO2.Through the construction of band structural engineering (such as doping, ligand substitution, heterojunction construction) may achieve the capture of stronger light, higher gas adsorption, product selectivity, stability and photocatalytic efficiency;and improve catalytic efficiency through functionalization of synergistic catalytic effect and MOFs structure design. In addition, based on these researches of this area, we make suggestions for the future directions of MOFs photocatalytic reduction CO2.
