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.
