Abstract
Pristine MoS2 nanosheet/silver nanoparticles (MoS2/Ag NPs) and composites are fabricated via hydrothermal, green synthesis, and chemical methods. Pristine MoS2, Ag, Z/M, and Z/M/Ag nanoparticles and composites are characterized through SEM, FTIR, as well as UV-Vis spectroscopy. The bandgap of materials is reduced effectively which is useful for photocatalytic activity. The photocatalytic decomposition of pharmaceutical drugs in effluent has been researched using metal-oxide or metal-sulfide-based semiconductor nanoparticles as nano-catalysts. The originality of these nano-catalyst substances lies in their relative simplicity of manufacturing, capacity to absorb energy in the UV-visible spectrum, large bandgap, innoxious, and inexpensive. The visible-light photocatalytic activity of Z/M also Z/M/Ag composites were investigated using a test of OTC. Almost degradation of OTC in about 120 min. at different concentrations of composites, Z/M/Ag photocatalyst was attained. This substantial enhancement in the photocatalytic proficiency of Z/M/Ag photo-catalyst below visible light ir-radiation may be ascribed to existence of MoS2 and Ag micro-particles on ZnO micro-particles which significantly improves absorption in an observable scale of the visible range.
