Photocatalyst, environmental pollution, environmental protection.Abstract
At present, due to the overuse of resources in the process of human development and the neglect of the concept of green development, environmental pollution has become increasingly serious, which has become a major problem to be solved all over the world. Common environmental pollution, such as wastewater pollution, air pollution and bacterial pollution, pose a great threat to the ecological environment and human health. As a material emerged in the 1930 s, photocatalyst has been proved to be able to effectively degrade a variety of inorganic and organic pollutants, and most of the reactions are green and environmentally friendly. It will not produce more pollutants, can effectively alleviate the environmental crisis, and is widely used in antibacterial, resource development and other fields. This paper mainly introduces the preparation methods of three common photocatalysts, the mechanism of TiO2 photocatalyst, and the application of photocatalyst in environmental governance.
