摘要: 在无表面活性剂微乳液中制备了ZIF-8材料,并采用光致还原法将纳米Ag负载于ZIF-8表面,制备了负载量不同的系列Ag/ZIF-8复合材料。XRDSEMXPS UV-DRS以及光电性能测试表明Ag成功负载到ZIF-8中,且光电性能大幅度提高。对比考察了ZIF-8Ag/ZIF-8对有机染料的光降解效率,提出了光催化机理。由于Ag纳米粒子和ZIF-8的协同效应,其所形成的异质结构Ag/ZIF-8表现出了优异的光催化活性。

Abstract: In this work, Ag/ZIF-8 with high photocatalytic activity was facilely synthetized by integrating ZIF-8 and Ag, in which the ZIF-8 nanoparticles were synthesized using a reverse SFME route for the first time. The prepared photocatalyst was characterized by SEM, XRD, XPS, UV-DRS and electrochemical workstation. Results showed that Ag nanoparticles have successfully assembled on the surface of ZIF-8 and exhibit excellent electrochemical properties. Subsequently, Ag/ZIF-8 was employed as a visible-light photocatalytic material for degradation of organic dyesand the possible reaction mechanism was proposed. Owing to synergic effect between ZIF-8 and Ag and the hetero-junction structure, the unique Ag/ZIF-8 composite exhibited highly efficient photocatalytic degradation performance.


Key words: Ag/ZIF-8 compounds; surfactant-free microemulsion; photocatalytic degradation.
