摘要：Environmental pollution and energy deficiency represent major problems for the sustainability of the modern world. Photocatalysis has recently emerged as an effective and environmentally friendly technique to address some of these sustainability issues,although the key to the success of this approach is dependent on the photocatalysts themselves. Based on their attractive physic chemical properties,including their ultrahigh surface areas,homogeneous active sites and tunable functionality,metal-organic frameworks（MOFs） have become interesting platforms for the development of solar energy conversion devices. Furthermore,MOFs have recently been used in a wide variety of applications,including heterogeneous photocatalysis for pollutant degradation,organic transformations,hydrogen production and CO2 reduction. In this review,we have highlighted recent progress towards the application of MOFs in all of these areas. We have collected numerous reported examples of the use of MOFs in these areas,as well as providing some analysis of the key factors influencing the efficiency of these systems. Moreover,we have provided a detailed discussion of new strategies that have been developed for enhancing the photocatalytic activity of MOFs. Finally,we have provided an outlook for this area in terms of the future challenges and potential prospects for MOFs in photocatalysis.

摘要：Magnetically recyclable porous sodium dodecyl sulfate(SDS)/Fe2O3 hybrids,which combine the porous structure of Fe2O3 and hydrophobicity of SDS,have been successfully synthesized for the first *** Fe2O3 has been first pyrolyzed from MIL-100(Fe)using a simple two-step calcination ***,the obtained porous Fe2O3 nanoparticles have been self-assembled with SDS molecules and yielded hydrophobic SDS/Fe2O3 *** porous SDS/Fe2O3 hybrids have been demonstrated to be highly efficient for the denitrification of pyridine under visible light *** pyridine removal ratio has reached values as high as 100%after irradiation for 240 *** the results of a series of experimental measurements,it was concluded that the superior photocatalytic performance of SDS/Fe2O3 hybrids could be attributed to(i)the fast electron transport owing to the unique porous structure of Fe2O3,(ii)the superior visible light absorption of Fe2O3 nanoparticles,and(iii)the“bridge molecule”role of SDS efficiently improving the separation and transfer across the interfacial domain of SDS/Fe2O3 of photogenerated electron-hole *** significantly,after the catalytic reaction,the SDS/Fe2O3 hybrids could be easily recovered using magnets and reused during subsequent cycles,which indicated their stability and recyclability.

摘要：在相对温和的反应条件下,利用简单的反应过程将CO_(2)固定,形成高附加价值的产物,是当前很受关注的一项科学技术挑战,其中环氧丙烷和CO_(2)的环加成反应是实现碳中性,固定CO_(2)的一条理想途径,CO_(2)的有效活化则是这个反应的前提。但目前关于实验的反应过程和机理仍然是有待解决的问题。因此,在本研究中,我们通过合成不同金属基底的MOFs材料,分别进行CO_(2)与环氧丙烷的加成反应,分析最有利于反应进行的催化材料。实验结果表明,UiO-66-NH2的催化效果最好。本研究为不同材料的CO_(2)环加成反应的设计和应用提供一些新思路。
