Facile Synthesis of Magnetic Reduced Graphene Oxide-ZnFe2O4 Composites with Enhanced Visible-Light Photocatalytic Activity

Magnetic ZnFe2O4-the reduced graphene (rGO) nanocomposites (ZnFe2O4-rGO NCs) have been successfully synthesized by a facile solvothermal method. The photocatalytic activities of the prepared photocatalysts were evaluated by degradation of methylene blue (MB) dyes under visible-light irradiation. In...

Description
Summary:Magnetic ZnFe2O4-the reduced graphene (rGO) nanocomposites (ZnFe2O4-rGO NCs) have been successfully synthesized by a facile solvothermal method. The photocatalytic activities of the prepared photocatalysts were evaluated by degradation of methylene blue (MB) dyes under visible-light irradiation. In comparison with ZnFe2O4 nanoparticles(NPs) catalyst, the ZnFe2O4-rGO NCs can generate more hydroxyl radicals (*OH) via photoelectron chemical decomposition of H2O2. Moreover, the as-prepared ZnFe2O4-rGO NCs can magnetically separable in a suspension system. Therefore, they can be conveniently applied to dispose toxic organic pollutants during water treatment.
