Abstract

Forest-like BiFeO3 film formed through electrophoretic deposition of a prepared sol over stainless steel mesh, for the first time. The resultant film characterized by X-ray diffraction -XRD-, scanning electron microscopy -SEM- combined with energy-dispersive X-ray spectroscopy -EDS-, atomic force microscopy -AFM- and magnetic force microscopy -MFM-.Thephoto-electrochemical studiesshowthatthecurrentandopencircuitpotentialmovedto positive values under visible light. This explained by the fact that BiFeO3 film generates photo-induced electrons and produce photocurrent and photovoltage. Finally, as prepared thin film used for photocatalytic degradation of phenol in a photocatalytic reactor. The morphology has a significant role on the photocatalytic efficiency due to enhance light-harvesting feature and provide multi scattering centers. Forest-like film was included nanobranches with diameter of 100–150nm that offer pathways to facilitate electron transfer to substrate. In photocatalytic studies,the effectofimportant parameterssuch asinitial phenolconcentration, addition ofH2O2,and rotating speed investigated on the photocatalytic efficiency.
