AbstractA novel, practicable and convenient route has been developed to prepare polymer nanospheres embedded with CdS nanoparticles which show an extremely high photocatalytic activity compared with other photocatalysts. In this method, polymer nanospheres were fabricated through the polymerization of cadmium dimethacrylate which was introduced into self-assembly system of chitosan and 3-mercaptopropionic acid. Then CdS nanoparticles were prepared insitu by inflating H2S into the polymer nanospheres.

Excellent Photocatalytic Activity

A ZnO/CdS/Cu2S composite photocatalyst with high photocatalytic activity was successfully synthesized by a three-step process. The results of XRD, XPS, SEM, and UV–Vis analysis show that ZnO nanosheets were successfully compounded with CdS nanoparticles, and the surface of CdS was successfully modified by Cu2S under ultraviolet light. Photocatalytic measurements were carried out and the results show that the photocatalytic efficiency of ZnO/CdS/Cu2S reached 95%. Compared with ZnO ([Formula: see text][Formula: see text][Formula: see text]), the kinetic constant of ZnO/CdS/Cu2S was up to [Formula: see text][Formula: see text][Formula: see text], which shows its excellent photocatalytic activity. A photocatalytic mechanism was proposed to illustrate the high activity separation efficiency.
