摘　　要：以AgNO_(3)、聚乙烯吡咯烷酮(PVP)、钛酸四正丁酯、石墨烯等为原料,利用溶剂热法合成AgCl/TiO_(2)/GO复合光催化剂,经紫外光照还原得到Ag@AgCl/TiO_(2)/GO,并将其应用于罗丹明B的太阳光催化降解反应中。结果表明,该催化剂具有较高的光催化活性和稳定性。在100 mL 3 mg·L^(-1)罗丹明B溶液中,投加0.5 g·L^(-1)的Ag@AgCl/TiO_(2)/GO催化剂,光照75 min后,罗丹明B降解率高达98%以上。In this paper,AgCl/TiO_(2)/GO composite photocatalyst was synthesized by solvothermal method from AgNO_(3),polyvinylpyrrolidone(PVP),tetra-n-butyl titanate,graphene,etc.,and was reduced to Ag@AgCl/TiO_(2)/GO by ultraviolet light.By being exposed to sun in degradation of RhB by,it was verified that the activity and stability of Ag@AgCl/TiO_(2)/GO photocatalyst were high.After 75 min of illumination,the degradation of RhB was up to 98%when 0.5 g·L^(-1)Ag@AgCl/TiO_(2)/GO catalyst was added to 100 mL 3 mg·L^(-1)RhB solution.
