Review of the Application of TiO2 in the Field of Photoelectric Catalysis

Industrial wastewater contains many substances harmful to the human body. Many traditional treatment technologies have poor treatment effects and are difficult to meet standards. TiO2 photocatalytic technology has the advantages of strong oxidizing ability, no selectivity and no secondary pollution. It is widely used in the treatment of high concentration, refractory and toxic and harmful organic wastewater, and has achieved remarkable results. Based on photoelectrocatalytic technology, this paper outlines the development mechanism of photoelectrocatalytic oxidation technology and photocatalytic technology, summarizes the development and application of new photoelectrocatalytic materials in recent years, and forecasts the development prospect of photoelectrocatalytic water treatment technology.
