[0002] There are many types of catalysts, which can be divided into liquid catalysts and solid catalysts according to their state, and into homogeneous catalysts and heterogeneous catalysts according to the phase of the reaction system. Homogeneous catalysts include acids, bases, soluble transition metal compounds and peroxide catalysts. Catalysts occupy an extremely important position in the modern chemical industry. For example, in sewage treatment, water treatment catalysts can accelerate the oxidation and decomposition of organic matter, reduce COD, BOD and other indicators, and improve water quality. In drinking water treatment, water treatment catalysts can remove harmful substances in water, such as heavy metals, organic matter, etc.
