Catalysts are species that function to selectively speed up chemical reactions, and their application is frequently used to regulate chemical and biological processes. Numerous crucial industrial chemical processes and biological transformations would be impossible to carry out without catalysts and enzymes. In addition to drastically reducing the energy required for some chemical processes, catalysts may also be used to selectively break down environmental pollutants. As a result, they play a significant role in the development of sustainable approaches to social, economic, and industrial growth. Understanding present catalytic systems, improving current catalytic processes, and even investigating whole new chemical transformations made possible by catalysis are all active areas of inquiry for several research teams.
