摘要
利用光催化降解甲基橙的脱色率来表征WS_2/TiO_2/绢云母复合物的催化特性。与其他催化剂比较,WS_2/TiO_2/绢云母复合物催化降解有机物效果更好。同时研究了WS_2/TiO_2/绢云母复合物在不同pH值、不同光照等条件下的催化性能,找到该复合物最佳的催化降解有机染料的条件。
The catalytic properties of WS_2/TiO_2/mica compound was characterized by the degradation rate of methyl orange.Compared with different catalysts, WS_2/TiO_2/mica compound was the best the catalytic properties to decompose organic matter.This paper showed that the optimum conditions was the catalytic properties of WS_2/TiO_2/mica compound decomposed organic matter.
