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.XRD、SEM、XPS、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-8和Ag/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 re-verse SFME route for the first time.The prepared photocatalyst was characterized by SEM,XRD,XPS,UV-DRS and electrochemical workstation.Results showed that Ag nanoparti-cles 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 dyes,and 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.
