The toxic organic pollutants present in the environment is a serious anxiety to human and other living organisms. The quality of water is destroyed by the appearance of these organic pollutants in water bodies which makes it unsuitable for utilisation and majority of these contaminant are not manageable in nature due to their inefficient removal by conventional technology. Hence, the photocatalytic oxidation process attracts the attention of researchers as this process produces reactive oxygen species which are capable of performing absolute mineralisation of the organic pollutant present. Nowadays, many nanomaterials are discovered by researchers which show photocatalytic activity. Among them Bismuth Ferrite, BiFeO3 (BFO) having perovskite type structure has been emerged as subject of investigation as a photocatalyst as its multiferroic behaviour at room temperature which promote the charge carrier separation. It has also small band gap and chemical stability. But BFO have limited ability to degrade organic pollutant photocatalytically, as it has inefficient absorption of light in the visible region and large rate of recombination of charge carrier. There are many methods to overcome this limitation in which doping and nanocomposite formation are important one. This chapter will give a concise description of the structure, synthesis, characterisation and properties of perovskite type BFO and discuss the strategies to improve the photocatalytic activity of BFO by doping and nanocomposite formation for environmental remediation.
