Title
Praseodymium-doped ZnS nanomaterials: Hydrothermal synthesis and characterization with enhanced visible light photocatalytic activity
Type of Research Article
Keywords
Praseodymium ZnS Nanocatalyst Decolorization Nanoparticle
Abstract
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 > CO3 2 > isopropyl alcohol. The Langmuir–Hinshelwood (L-H) adsorption and rate coefficients for the photocatalytic process were successfully established.
