Abstract
BiFeO3 (BFO) is the most promising of this rare ABO3-type perovskite multiferroic materials because it exhibits in bulk BFO’s with high ferroelectric Curie temperatures (TC = 1103 K) and G-type antiferromagnetic Neels (TN = 643 K), multiferroic behavior can be observed at room temperature. It is lead-free, possesses fascinating multiferroic and optical properties, and is environmentally benign. Recent investigations on BFO have shown that it forms an excellent visible light-responsive photo-catalytic material due to its band gap of 2 eV and the remarkable stability of chemicals. In this manuscript we have tried to explain the improvement in the multiferric and photocatalytic properties of BFO by substitution on A and B site. The various synthesis processes along with their impact, the types of doping and their impact on the structural changes and thereafter these impact results in the improvement in the properties has been explored in the manuscript.
