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.
HIGHLIGHTS
- An approach rare earth materials Gd & Ce doping in BiFeO3
- Photocatalytic activites and Degradation constants well explained with graphs
- Gd (0.1 wt%) and Ce (0.1 wt%) doped BiFeO3 showed less photodegradation time than pure BiFeO3 & other doping concentrations
- Bi9Gd0.1Fe0.9Ce0.1O3 has enhanced photocatalytic degradation for Rhodamine B
- Degradation of Rhodamine B for the sample BFO is about 50 % and for Gd (0.1 wt%) and Ce (0.1 wt%) doped BiFeO3 is very high that is almost 90 %
