Influence of Nickel, Silver, and Sulphur Doping on the Photocatalytic Efficiency of Mesoporous ZnO Nanoparticles

Abstract

Silver-, nickel-, and sulphur-doped mesoporous ZnO are prepared as an efficient photocatalyst through the hydrothermal technique using F127, nickel nitrate, silver nitrate, thiourea, and zinc nitrate hexahydrate. Availability of mesoporous morphology with nanocrystallite size range is established by nitrogen adsorption–desorption isotherm and X-ray diffraction study. Impact of doping on optical properties is explored by UV–vis and PL spectra study and proclaimed that band gap energy and recombination rapidity fall with rising doping portion. Endorsement of porous assembly with crystal size and shape is executed by SEM and TEM images. Silver, nickel, and sulphur show their occurrence in ZnO via EDX spectra. The competence of the formulated photocatalyst is checked toward three different dyes.
