Advanced catalytic and biomedical applications of silver functionalized SnCuO3 nanocomposites synthesized through novel surfactant mediated chemical approach

Abstract

In the current contribution, silver impregnated and un impregnated bimetallic oxide nanocomposites of SnCuO₃ were synthesized by a novel surfactant mediated chemical approach. The tween-80 was used as a surfactant to effectively modulate the morphological features of the nanocomposites. The synthesized nanocomposites were characterized by XRD, HRTEM, SEM, EDX, FTIR and XPS. The results revealed the rod-shaped surface morphology of the nanocomposites with length and diameter of 245 nm and 66 nm respectively. The synthesized nanocomposites were tested for catalytic and biomedical applications. The rate of catalytic degradation reaction of methylene blue by the SnCuO₃ and Ag/SnCuO₃ nanocomposites were found to be 10.2 and 8.5 respectively. Only in 10 min all the dye molecules were degraded. The synthesized nanomaterials SnCuO₃ and Ag/SnCuO₃ are potent antileishmanial agents having CC₅₀ value 12728.03 and 3001.70 µg/mL respectively that were found to be biocompatible with very low toxicity as revealed by their hemolytic activity results. Moreover, the nanostructures exhibited promising antibacterial properties by effectively inhibiting the growth of both E. coli and S. aureus bacteria through photoinhibition. When subjected to visible light irradiation, the growth inhibition zone of Ag/SnCuO₃ against E. coli and S. aureus was measured at (15 ± 0.4 mm) and (17 ± 0.3 mm), respectively. These nanostructures demonstrated the ability to impede bacterial proliferation and viability, underscoring their potential for use in water disinfection and as antibacterial coatings utilizing Ag/SnCuO₃.
