Self-Assembled ZnIn_(0.16)Ag_(2x)S_(1.24+x) (x = 0-0.025) Nanospheres by a Simple Hydrothermal Method as Visible Light-Driven Photocatalysts

摘要

A single-step and facile hydrothermal route has been developed for the fabrication of ZnIn_(0.16)Ag_(2x)S_(1.24+x) (x = 0-0.025) nanospheres. The photocatalytic activities of the products for the H2 evolution from aqueous solutions containing sacrificial reagents, SO_3~(2-) and S~(2-), were investigated under visible-light irradiation (λ > 400 nm). It was found that the photocatalysts showed high photocatalytic activities even without Pt co-catalysts.
