摘　　要：采用重构法制备了BiOCl/ZnAl-LDHs复合光催化剂,利用XRD、BET进行了表征。探讨了Bi/Al摩尔比、pH对复合光催化剂结构和可见光催化性能的影响。结果表明,重构法可以制备出结构完整的BiOCl/ZnAl-LDHs催化剂,当pH=9,Bi/Al摩尔比为1/3条件下制备的BiOCl/ZnAl-LDHs催化剂可见光性能较好,对罗丹明B的降解率达92.3%。The BiOCl/ZnAl-LDHs composite photocatalyst was prepared by reconstruction method. The prepared photocatalyst was characterized by XRD and BET technique. The effect of pH and Bi/Al molar ratio on the structure and photocatalytic performance of prepared photocatalyst was investigated. The results shown that BiOCl/ZnAl-LDHs with perfect layer structure could be prepared by reconstruction method, and BiOCl/ZnAl-LDHs prepared under pH of 9 and Bi/Al molar ratio of 1/3 presented good visible light catalytic performance, and Rh B degradation rate was above 90% with the photocatalyst under visible-light irradiation.
