Role of cooperative factors in the photocatalytic activity of Ba and Mn doped BiFeO nanoparticles.

The escalated photocatalytic (PC) efficiency of the visible light absorber Ba-doped BiFeMnO (BFM) nanoparticles (NPs) as compared to BiFeO (BFO) NPs is reported for the degradation of the organic pollutants rhodamine B and methyl orange. 1 mol% Ba-doped-BFM NPs degrade both dyes within 60 and 25 minutes under UV + visible illumination, respectively. The Ba and Mn co-doping up to 5 mol% in BFO NPs increases the specific surface area, energy of d-d transitions, and PC efficiency of the BFO NPs.
