Abstract

Highly visible light efficient photocatalyst; ferric oxide/zinc oxide/silicon nitride (Fe₃O₄/ZnO/Si₃N₄) nanocomposite has been designed. Its photocatalytic activity has been studied for the degradation of two dyes; sunset yellow and methyl orange from aqueous solution. Results showed high degradation rate of 90 and 96% for sunset yellow and methyl orange, respectively. Scavenging studies indicated the major involvement of [rad]OH radicals in the degradation process. Reusability study has been conducted for 6 consecutive cycles indicating its appreciable activity even after repetitive cycles. Antimicrobial activity studied against E. Coli and Pseudomonas strains showed an appreciable inhibition zone.
