Metal and Non-Metal Doped FeVO4 Based Composite Semiconductors for Degradation of Organic Toxicants: A Review

In recent years, two of the most pressing problems in the world have become the rising need for energy and the degradation of the environment. Industrialization’s discharge of organic and metal ion waste into water systems has created a critical demand for efficient removal and degradation of organic waste. Due to their superior optical and electrical properties, semiconductors like metal oxides and mixed metal oxides have attracted a lot of attention for photocatalysis. The majority of these semiconductors, however, lack the ideal band alignment necessary for effective sun/solar light absorption. FeVO₄ can be a useful tool for band tuning for visible light photocatalysis in order to get around this problem. Many attempts have been made over the years to increase FeVO₄’s photocatalytic performance. It has been postulated and put into practice that a number of different modification strategies, including element doping and composite fabrication, can be utilized to increase the efficiency of photocatalysts based on FeVO₄. The photocatalytic degradation of harmful organic pollutants by various metal- and non-metal-doped FeVO₄-based materials is highlighted in this review paper. In recent years, significant progress has been made in understanding the core problems and creating effective photocatalysts.
