Effect of Gd and Ce Doped BiFeO3 for Photocatalytic Activity

Abstract

In this current research work deals with the synthesis, characterization and photocatalytic activity of gadolinium (Gd) and cerium (Ce) doped bismuth ferrite oxide BiFeO3 (BFO). All the samples BFO, BGF-1, BGCF-1, BGCF-2 and BGCF-3 were synthesized by sol-gel method. The structural analysis carried out by X-ray diffraction (XRD), surface morphology examined by field emission scanning electron microscopy (FE-SEM) with EDAX and transmission electron microscopy (TEM), the magnetic properties investigated using vibration sample magnetometer (VSM) and their photocatalytic activity was evaluated by Rhodamine B (RhB) dye under visible light irradiation. The results found that the Gd (0.1 wt.%) and Ce doped (0.1 wt.%) BFO showed better photocatalytic activity as compared to BFO and other samples.
