The development of new, high-efficiency catalysts is the basis for the leapfrog development of the petroleum and chemical industries. In recent years, nearly 50% of the international research on catalysis has been focused on the development of new catalysts, and increasing attention has been paid to them.

The main function of catalysts is to reduce the activation energy of chemical reactions and speed up the reaction rate, so they are widely used in oil refining, chemical, pharmaceutical and environmental protection industries. Technological advances in catalysts are one of the most effective driving
