The main intent of this work is to reduce the demerits of sulfur (S) doped TiO2 nanoparticles preparation, in requisites of the simple, cost effective, and mass preparation parameters. The physicochemical

The observed results shows the smaller crystallite size (10–12 nm) with spherical morphology of individual grains based on the XRD, SEM and TEM analysis results. From the UV-Visible and PL analyses, it observed that the S doped TiO2 has been improved the UV and Visible absorption. The optimized results were exhibits sulfur doping escalating the photogenerated electrons and holes during the photocatalytic reaction. The obtained nanoparticles can be utilized in photovoltaic devices as photoanode material
