摘要：

Pr-doped ZnS nanoparticles with variable praseodymium contents were successfully synthesized via a hydrothermal process. The products were characterized by XRD, SEM, TEM, XPS, TGA and UV-vis techniques. The photocatalytic performance of the as-synthesized nanoparticles was investigated for the decolorization of Reactive Blue 19 solution under visible light irradiation. The highest decolorization was achieved with 3% Pr-doped ZnS nanoparticles. The order of inhibitory effect of radical scavengers was butanol > Cl- > CO32- > isopropyl alcohol. The Langmuir-Hinshelwood (L-H) adsorption and rate coefficients for the photocatalytic process were successfully established. (C) 2015 The Korean Society of Industrial and Engineering Chemistry.
