摘要

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