ABSTRACT

In this work, we present Co3S4-SnO2 supported polyvinylpyrrolidone-cellulose (PVPCS) nano-structure for Lidocaine degradation. The nanostructure was characterized by various techniques i.e. morphological and optical ones. The results have demonstrated that Co3S4-SnO2 nanocomposites were evenly supported on the PVPCS. Moreover, the photocatalysis performances of the catalysts were investigated under ultra-violet (UV) light irradiation. The nano-structure Co3S4-SnO2/PVPCS composite (98.72%) revealed the highest photocatalysis performance as compared to SnO2 nanoparticles, and Co3S4-SnO2 nanocomposites. The photo-stability of nano-structure Co3S4-SnO2/PVPCS composite was characterized using cyclic catalytic experimental. Results demonstrated a substantially stable performance of the nano-structure Co3S4-SnO2/PVPCS composite. The biological properties of Co3S4-SnO2/PVPCS composite were investigated through the antibacterial (versus Staphylococcus aureus, and Escherichia coli) and antifungal studies (Candida albicans). As the results declared, Co3S4-SnO2 nanocomposites have substantial biological properties as compared to SnO2 nanoparticles, and Co3S4-SnO2 nanocomposites.
