摘要：本文将反胶束法制备的CdS晶体键合在经γ 巯丙基三甲氧基硅(MPTMS)修饰的P25粒子的表面.产物P25 MPTMS CdS复合粒子的紫外 可见吸收和粒子形貌分别用漫反射光谱仪和透射电镜进行了表征.同时也进行了光催化降解甲基橙溶液的实验,发现P25 MPTMS CdS在紫外和可见光下区域都具备较高的光催化活性.经过18h的可见光照后(λ>400nm),紫外 可见光谱表明,P25 MPTMS CdS粒子具备较好的光稳定性.
CdS nanocrystallites prepared in reverse micellar systems were immobilized onto P25 particles which had been modified by 3-mercaptopropyltrimethoxysilane(MPTMS).The resulting P25-MPTMS-CdS particles were characterized by UV-Vis spectra and TEM.Their photocatalytic activity for the degradation of methyl orange dye was investigated.The results indicate P25-MPTMS-CdS photocatalysts have high photocatalytic activities both within UV and visible range.After 18 h of photoirradiation(λ>400 nm),the UV-Vis spectra show that CdS nanoparticles are well resist to photoirradiation,and have good photostability.
