Influence of Cu on the photocatalytic activity of ZnS nanoparticles

摘要

The synthesis of Cu doped ZnS particles by ion-exchange method and the influence on workable wavelength of light is reported. The workable wavelength of Cu doped ZnS was extended from the same of ZnS (310 nm). The photocatalytic activity of Cu doped ZnS was measured by hydrogen generation experiment using solar simulator and the highest apparent quantum yield was about 11% given from 1% Cu doped ZnS.
