“…BiFeO 3 is one of the important perovskite-type oxides with a narrow band gap of 2.1–2.5 eV, which is suitable for the response of visible light. BiFeO 3 is shown to be a promising photocatalyst for dye degradation, as well as water splitting under visible-light irradiation [20,21,22,23,24,25,26,27]. Furthermore, BiFeO 3 also exhibits favorable visible-light-driven photo-Fenton degradation activity [28,29].…”

Z-scheme Ag2S/BiFeO3 heterojunction composites were successfully prepared through a precipitation method. The morphology and microstructure characterization demonstrate that Ag2S nanoparticles (30–50 nm) are well-decorated on the surfaces of polyhedral BiFeO3 particles (500–800 nm) to form Ag2S/BiFeO3 heterojunctions. The photocatalytic and photo-Fenton catalytic activities of the as-derived Ag2S/BiFeO3 heterojunction composites were evaluated by the degradation of methyl orange (MO) under visible-light irradiation. The photocatalytic result indicates that the Ag2S/BiFeO3 composites exhibit much improved photocatalytic activities when compared with bare Ag2S and BiFeO3. The optimum composite sample was observed to be 15% Ag2S/BiFeO3 with an Ag2S mass fraction of 15%. Furthermore, the addition of H2O2 can further enhance the dye degradation efficiency, which is due to the synergistic effects of photo- and Fenton catalysis. The results of photoelectrochemical and photoluminescence measurements suggest a greater separation of the photoexcited electron/hole pairs in the Ag2S/BiFeO3 composites. According to the active species trapping experiments, the photocatalytic and photo-Fenton catalytic mechanisms of the Ag2S/BiFeO3 composites were proposed and discussed.

“…The composite material band gap value was reduced compared to sole BiFeO 3 and Bi 2 WO 6 which results in better dye degradation efficiency. 54% degradation efficiency was obtained at 2.28 eV for MB dye 23,25,72,73 degradation and 36% degradation efficiency was obtained at the same bandgap value for RhB dye degradation. 23 It is much higher than sole BiFeO 3 and Bi 2 WO 6 and the results are shown in Table X.…”

ABO3 perovskite-type multifunctional BiFeO3 material is a good candidate for a variety of device applications such as photocatalyst, gas sensor, biosensor, thermoelectric material, and so on due to its remarkable magnetoelectric coupling property. The future scope of this perovskite material can be broadened by its cost-effective, highly efficient, and easily available nature. Herein, we discuss recent developments in multifunctional BiFeO3 based on two crucial applications such as sensors and photocatalyst from the recent research literature. We have also addressed the effects of doping which includes the bandgap reduction, finer pore size, and crystallite size leading to higher efficiency. Additionally, the BiFeO3 composites due to their larger surface area involve more active molecules on the surface thereby increasing the efficiency even more. Finally, some of the future scopes of the research are also addressed in this article.

“…Guo et al synthesized bismuth ferrite photocatalysts with different morphologies by changing the concentration of citric acid in the precursor solution during the hydrothermal process. 17 Liu et al proposed an industrially scalable strategy to fabricate SmMnO 3 perovskite catalysts through a simple molten polymerization method using citric acid as an additive. The morphology of SmMnO 3 can be adjusted to net-like and granular-like structures by controlling the amount of citric acid.…”
