    Direct discharge of waste, including organic dyes from various industries into the water bodies contributes significantly to environmental contamination. A detail research on the photocatalytic materials is much needed that may successfully remove the harmful pollutants from water in order to make water free from such dangerous contaminants. In this respect, CoS based photocatalysts have drawn a lot of attention because of their good stability, excellent conductivity, and relatively small band gap. In the current project, CoS nanoparticles, a series of Ni doped CoS (Ni-CoS) nanoparticles with varying percentage of Ni, and a series of Ni-CoS nanoparticles were made composite with sulphur doped graphitic carbon nitride (Ni-CoS/SCN) with varying concentrations of SCN using an easy, efficient, and affordable co-precipitation technique; however, SCN was synthesized through a thermal degradation process using thiourea as a precursor. Evaluation of synthesized photocatalysts was carried out by cutting edge techniques i.e.; FTIR and XRD. Photocatalytic degradation behaviour of the as prepared photocatalysts was observed by UV-Visible spectrophotometer and the doping of Ni-metal was thought to have contributed to the high rate of degradation of methylene blue, which was used as a standard pollutant dye. The greatest outcomes for doped NPs were from 6% Ni-CoS NPs. while the best photocatalytic activity was achieved by 6Ni-CoS@50 SCN NCs. EIS spectra for CoS, 6% Ni-CoS and 6Ni CoS@50 SCN was observed and they were examined for their antimicrobial performance as well.
