摘要 以聚苯乙烯(PS)微球为模板,聚乙烯比咯烷酮为偶联剂,用超声化学法合成了核壳型PS/CdS纳米复合光催化剂(1),其结构,形貌和光催化性能经FT-IR,UV-Vis,XRD,SEM,TEM和EDS和表征。考察了反应时间(t)和物料比r[n(S2-)∶n(Cd2+)]对1rt形貌的影响。在最佳反应条件[Cd(Ac)228mmol,r=1.4,于室温超声反应3.0h]下制备的11.43.0具有明显的核壳结构,颗粒均匀呈球形,分散性好,平均粒径约320nm。11.43.0光催化罗丹明(RhB)降解反应结果表明,70min脱色率达到100%。 A core-shell structure composite photocatalysts( PS / CdS,1) was synthesized by facile ultrasonic method,using PS as the model and PVP as the coupling agent. The structures and photocatalysis activity were characterized by UV-Vis,FT-IR,XRD,SEM,TEM and EDS. Effects of reaction time and mole ratio on the microstructure of 1 were investigated. The optimum reaction conditions of 1 were as follows:Cd( Ac)2was 28 mmol,n( Cd^2 +) ∶ n( S^2-) =1.0 ∶ 1.4 and reaction time was 3 h. The results of photocatalyzing Rh B degradation indicated that the decolourization ratio was 100% after 70 min.
