Photo-catalytic Degradation of Methyl Orange Dye using ZnS and N-doped ZnS Nanoparticles under Visible Radiation

摘要

ZnS and N-doped-ZnS nanoparticles were prepared by aqueous chemical method under optimal conditions and characterized using XRD, TEM and UV-Visible spectroscopic techniques. As-synthesized nanomaterials were used as a photo-catalysts for the degradation of Methyl Orange (MO) dye. Effects of photo-catalyst load, pH, and substrate initial concentration on degradation of the dye in aqueous solution have been investigated. Maximum degradation (76.56 ) of methyl orange was observed using optimum pH 6 and catalyst load 250 mgL~(-1).
