金属有机框架复合材料光催化研究进展

Research Progress on Photocatalysis of Metalorganic Framework Composites

摘要: 金属有机框架(MOFs)材料已经成为光催化领域的研究热点。MOFs作为多孔材料，具有大的比表面积，有序的孔道结构，易于功能化等优势。然而，由于其较差的光捕获能力和稳定性，限制了其在光催化领域的应用。为了解决这个问题，研究人员开始将客体物质引入到MOF中，形成MOF复合材料。通过活性界面的构建和功能单元的引入，有针对性地优化了光吸收能力、电荷分离和反应活性，从而提高了整体光催化性能。此外，该复合材料具有多种活性位点，具有明确的配位构型，有利于光催化机理的研究。本文主要论述了MOF复合材料的类型，并介绍了它们在光催化分解水、CO2还原和有机反应中的最新应用。

Abstract: Metalorganic framework (MOFs) materials have become a research hotspot in the field of photoca-talysis. As a porous material, MOFs have the advantages of large specific surface area, ordered pore structure and easy functionalization. However, due to its poor light trapping ability and stability, its application in the field of photocatalysis is limited. To solve this problem, the researchers began to introduce guest matter into the MOF, forming MOF composites. Through the construction of active interface and the introduction of functional units, the light absorption capacity, charge separation and reactivity are optimized, and the overall photocatalytic performance is improved. In addition, the composite has a variety of active sites and a clear coordination configuration, which is beneficial to the study of photocatalysis mechanism. This work mainly discusses the types of MOF composites, and introduces their latest applications in photocatalytic water decomposition, CO2 reduction and organic reactions.
