Tungsten Heteropoly Acid Photocatalyst
A tungsten heteropoly acid phtocatalyst is composed of heteropoly acid and its salt, it consists of a central (hetero) atom (P, Si, etc.) and a coordinated (multi) atom W. A group of metal complexes of oxygen groups bridged by oxygen atoms into space, which can be widely used in homogeneous and heterogeneous catalysis systems. Because of the development of petrochemical industry, especially the fine chemical industry, the multifunction of catalysts has become a new research target, tungsten heteropoly acid photocatalyst is a bifunctional catalytic material with acidity and basicity and redox property. It is an environmentally friendly catalyst and can reduce environmental pollution and equipment corrosion. Therefore, it is of great significance to study the new catalytic process. Under visible light or UV irradiation, tungsten heteropoly acid is excited to become a strong oxidant and can oxidize various organic compounds in water. Its photocatalytic activity is almo...
