investigation of mnfe₂o₄@zno-go and mnfe₂o₄@zno-rgo magnetic nanocomposites as an efficient photocatalyst under visible light irradiation

a facile hydrothermal synthesis route was used to synthesize mnfe₂o₄@zno–go and mnfe₂o₄@zno–rgo nanocomposites at low temperature of 180 °c for 3h. our synthesis of mnfe₂o₄@zno modified by the different weight percentages of go and rgo. the assynthesized samples were investigated by techniques xrd, fe-sem, tem, bet. magnetic studies demonstrated that the mnfe₂o₄@zno–go and mnfe₂o₄@zno–rgo nanocomposites can be used as a magnetically separable photocatalyst. the photodegradation efficiency of the prepared materials was evaluated by the decomposition of congo red (cr) in 35 min of natural sunlight irradiation. among the synthesized materials, the mnfe₂o₄@zno-go photocatalyst showed maximum photocatalytic activity (99.54 %).
