Microwave-assisted synthesized and characterization of BiFeO3(CTAB/PEG/PVA) nanocomposites by the auto-combustion method with efficient visible-light photocatalytic dye degradation

A simple green route of bismuth ferrite (BiFeO 3 ) was prepared by a reaction an auto-combustion method with the addition of CTAB, PVA, and PEG surfactant. The microwave irradiation was operated by 900 W power under 2 min. The characterization of BiFeO 3 and BiFeO 3 (CTAB/PVA/PEG) nanocomposites has been performed by the XRD, FT-IR, PL, VSM, DRS, FE-SEM, CV, EIS, and UV–Vis spectroscopy analysis, respectively. The XRD analysis was displayed that highly crystallization nanocomposites with rhombohedral structure is obtained magnetization with Ms = 0.68 emu g −1 that has been found in VSM measurement analysis. The electrochemical measurements of the synthesized nanocomposites displayed a good performance at 100 mV.s −1 scan rate. Also, the optical properties indicated that the bandgap of samples was around ~ 2 in the visible range. Moreover, the photocatalytic performances of the BiFeO 3 (CTAB/PVA/PEG) nanocomposites have illustrated the degradation of methyl orange (MO) as typical organic dye pollution under visible-light irradiation of 10 W white LED lamp. Moreover, the experimental results showed that the BiFeO 3 -CTAB nanocomposite has the highest degradation of MO dye pollution was in aqueous solution increased to 97%.
