Recent trends and morphology mechanisms of rare-earth based BiFeO3 nano perovskites with excellent photocatalytic performances

The multiferroic bismuth ferrite (BiFeO3, denoted as BFO) semiconductors have attracted prominent recognition due to their unique physical properties and prospective industrial applications. Significant features like strong photo absorption and morphological structure play a major role in rare earth-based BFO materials. The article encapsulates the latest developments on rare-earth-based nano BFO as new class photo catalytic materials for electro-optic applications. Detailed discussion on degradation efficiencies of industrial organic dyes in ultra-violet, visible light, and near infra-red photocatalysis was carried out. The various techniques acquired to fabricate rare-earth-based BFO and the modification approaches in A- and B-site that take part in the morphology, and photo activity improvement were also detailed. This review also summarizes the existing state of research work and explains some practical ideologies of BiFeO3 for their future developments. Finally, this article discusses the summary and future aspects of the present challenges faced by the BFO based materials for feasible improvements.
