Facile synthesis of Fe3O4@SiO2 center dot Cu2O systenm and enhanced catalytic reduction of 4-nitrophenol

Herein, we describe a facile method to synthesize Fe3O4@SiO2.Cu2O catalyst. The as-prepared Fe3O4@SiO2.Cu2O structure was characterized by powdered X-ray diffraction (p-XRD), infrared spectroscopy (IR), field emission scanned electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX). The as-prepared catalyst were successfully used to reduce 4-nitrophenol to 4-aminophenol at ambient temperature in 5 minutes. The recycling experiments confirmed the stability and superior and superior catalytic efficiency of as synthesized catalyst..
