Microwave Combustion Synthesis, Structural and Morphological Properties of Mg-doped CoFe2O4 Nano-Magnetic Photocatalyst

Abstract

In the present study, pure and Mg-doped CoFe2O4 nano-magnetic photocatalyst was rapidly prepared based on a microwave-assisted method. Magnetic nano-catalyst are potent heterogeneous photocatalysts for degradation of methylene blue (MB) and promising alternatives to conventional catalysts used in wastewater treatments. Powder XRD, FTIR, HRSEM, EDS, and VSM were performed to identify the structure of Mg-doped CoFe2O4 . The optimal conditions for maximum degradation efficiency were confirmed. The degradation efficiency was also reported to be 87.85% under optimal conditions. Finally, nano-magnetic photocatalyst could be reused for six further runs without remarkable changes in catalytic efficiencies; after six runs, adequate reusability and chemical stability were observed
