<p>In this study, it is reported about the preparation of a MoS₂/Ag₃VO₄ nanocomposite with a simple synthesis approach. The nanocomposite is made up of two-dimensional MoS₂ nanosheets decorated with spherical Ag₃VO₄ nanoparticles. Both the structure and the morphology of the arranged nanocomposite were determined by XRD, EDAX, FESEM, and FTIR. Utilizing ultraviolet–visible spectroscopy, the optical characteristics of MoS₂/Ag₃VO₄ nanocomposite were investigated. After Ag₃VO₄ was incorporated upon MoS₂ nanosheets, optical transmission spectra clearly showed a red shift occurs in the band gap, which ultimately results in a better retention of visible light. This is brought about by the separating photogenerated charge carriers efficiently and the quick transfer of charge to the conduction band potential response sites of MoS₂ and Ag₃VO₄ nanoparticle. It has been found that the band gap of MoS₂/Ag₃VO₄ nanocomposite is 2.29&#xa0;eV, which is essentially quite contrasting from the band gap of MoS₂ (~ 2.42&#xa0;eV). According to the results, malachite green oxalate (MGO) and acridine orange (AO) dye has effectively fade out (by more than 80%) in one hour when exposed to visible light. Additionally, the MoS₂ interaction improves the photostability of the catalyst during the reaction by preventing photo-corrosion of the Ag₃VO₄. In order to obtain effective dye degradation, and also recyclability test of the photocatalyst for five consecutive times has been reported.</p>
