Magnetic detachable catalyst of Ag-decorated Fe3o4 nanocomposites using agro-waste extracts towards photocatalytic degradation of organic dye and their bactericidal effect
摘要
The aim of this study was to construct a magnetized detachable catalyst (MDC) of Ag-decorated Fe3O4 nanocomposites and evaluate their antibacterial efficacy and photocatalytic capabilities. The results showed that the Ag-decorated Fe3O4 nanocomposites displayed exceptional antibacterial efficacy towards Pseudomonas aeruginosa and high photocatalytic capabilities towards organic hue inhibition. The kinetics investigation revealed that the Ag@ Fe3O4 nanocomposites eradicated 99.9% of Rhodamine B at a rate variable of 1.89 min−1. The magnetically detachable catalyst was found to be reusable without affecting the efficiency of photocatalytic reactions. These findings suggest that the Ag@Fe3O4 nanocomposites have promising applications in wastewater treatment and biomedical research.
