Description
Summary:An affordable solid state reaction technique was used to make pure and Ni doped ZnS nanoparticles. FTIR, UV–Vis, XRD and SEM were used to characterise the products’ functional, Structural and morphological properties. The polycrystalline nature of the nanoparticles with cubic crystal structure was confirmed by X-ray diffraction. FTIR spectroscopy was used to analyse the functional group linked with a molecule’s vibration. The photocatalytic activity results showed that Ni doping increased ZnS’s photocatalytic activity. As a result, Ni-ZnS could be employed as a photocatalyst to degrade the environmental contaminant Methyl red dye. Among nanocomposites, ZnS have the highest photoactivity. To optimise the photodegradation process of dyes, the influence of sample pH and ZnS dosage were changed. With a concentration of 50 mg/l, Efficient degradation was obtained for Methyl red. In samples with a pH of 6-10, the ZnS indicates the stability.
