摘　　要：随着国民环保意识的提高,人们对废水中的染料所造成的危害越来越重视。研究开发了一种Ag(I)-C_(60)材料并使用其作为光催化剂,对染料X-3B的光催化降解作用进行了实验研究。结果表明:以Ag(I)-C_(60)作为光催化剂,在400~700 nm波长范围的可见光照射下,可实现对X-3B的光催化降解,X-3B的UV-Vis吸光度在0~12 min内逐渐降低。通过对光催化染料降解过程中得到的主要中间产物的质谱图和结构式进行分析,推测了光降解机理,为富勒烯有机金属配合物光催化机理提供新思路。With the improvement of environmental protection awareness,the harm caused by dyes in wastewater has attracted more and more attention.In this study,an Ag(I)-C_(60) material was developed and used as photocatalyst to experimentally study the photocatalytic degradation of dye X-3 B.The results show that Ag(I)-C_(60) can be used as photocatalyst to degrade X-3 B under visible light irradiation in the wavelength range of 400~700 nm.The UV-Vis absorbance of X-3 B gradually decreased from 0 to 12 min.In the process of photocatalytic dye degradation,the main intermediate products were obtained,and their mass spectrometry information and structural formula were analyzed.The mechanism of photo degradation was speculated,which provides a new idea for the photocatalytic mechanism of organometallic complexes of fullerenes.
