摘　　要：为利用太阳光光催化去除染料污水中多种染料,通过水热反应,成功制备出x%g-G-C_(3)N_(4)/Zn_(0.3)Cd_(0.7)S光催化剂。在可见光照射下,该催化剂能同时降解染料污水中甲基橙、刚果红、中性红和罗丹明B。5%g-G-C_(3)N_(4)/Zn_(0.3)Cd_(0.7)S经过80 min光照,对上述4种染料降解效率分别达到98.4%、98.4%、99.2%和99.3%,远高于单一g-C_(3)N_(4)和Zn_(0.3)Cd_(0.7)S。光催化降解循环实验表明5%g-G-C_(3)N_(4)/Zn_(0.3)Cd_(0.7)S具有良好稳定性。x%g-G-C_(3)N_(4)/Zn_(0.3)Cd_(0.7)S光催化剂在染料废水的净化方面具有潜在应用前景。In order to photocatalyticly remove various dyes in actual dye wastewater utilizing solar light,x%g-C_(3)N_(4)/Zn_(0.3)Cd_(0.7)S photocatalysts were successfully prepared through hydrothermal reaction.The photocatalysts si-multaneously degraded methyl orange,congo red,neutral red and rhodamine B in dye wastewater under visi-ble light irradiation.And after 80 minutes of light irradiation,the 5%g-C_(3)N_(4)/Zn_(0.3)Cd_(0.7)S showed the degrada-tion efficiency of 98.4%,98.4%,99.2%,and 99.3%for the aforementioned four dyes,respectively,which is much higher than the performance of single g-C_(3)N_(4) and Zn_(0.3)Cd_(0.7)S.The photocatalytic degradation cycle exper-iment showed that the 5%g-C_(3)N_(4)/Zn_(0.3)Cd_(0.7)S had good stability.Therefore,x%g-C_(3)N_(4)/Zn_(0.3)Cd_(0.7)S photocatalysts exhibits potential application in the purification of dye wastewater.
