The effects of Ag-ions on the physiochemical characteristics and visible-light catalytic activity of ZnS nanoparticles

Abstract

In this case of study, the pure and different weight percentages of Ag ions doped ZnS Nanoparticles were synthesized by beneficial solid-state reaction method. Further, the synthesized nanoparticle’s physiochemical properties were thoroughly examined by the appropriate characterization tools. The structural examination demonstrates that the synthesis of crystalline nanoparticles with an average crystallite size of 2.41 nm was reduced from 3.68 nm to 2.41 nm and increased further due to the influence of Ag-ions on ZnS matrix. The FT-IR investigation validated the Zn-S functional molecule presence. A considerable quantity of spherical-shaped nanoparticles with uniform distribution enhances the possibility of aggregation due to heterogeneous particle interactions. The optical research demonstrates that the bandgap wideness is decreasing due to Ag-ion interstitial secondary energy levels. Due to the limitations in charge carrier recombination caused by Ag-influences, the catalytic capability of ZnS nanoparticles under renewable sunlight irradiation is enhanced. As a result, the Ag-doped ZnS nano-catalyst degraded 95 % of the detrimental MO dyes within a short sun light irradiation period.
