Novel CdS photocatalytic nanomaterials were synthesized by a simple "one-pot" hydrothermal biomolecule-assisted method using glutathione (GSH) as the sulfur source and structure-directing reagent. HRTEM, FESEM, XRD, UV-Vis, PL, BET and photo-stimulated surface reaction technology were used to investigate the surface structure, photo absorption property and photocatalytic performance of CdS. Results show that various morphologies of CdS photocatalysts, such as solid nanospheres (s-CdS), hollow nanospheres (h-CdS) and nanorods (r-CdS), were obtained. The photocatalytic activity of s-CdS was superior to that of h-CdS and r-CdS under visible light. The excellent photocatalytic activity of s-CdS was ascribed to the small sizes of subnanocrystallites, which make it easy for photoinduced electrons and holes on the solid sphere to migrate to the surface and react with water and the sacrificial agent quickly.
