Introduction to Catalysis
Catalysis is a crucial field in chemistry and chemical engineering that involves the acceleration of chemical reactions by substances called catalysts. These catalysts are not consumed in the reaction and can be used repeatedly. Understanding catalysis is essential for various industrial processes, environmental applications, and the development of new materials. For those looking to delve deeper into this fascinating subject, numerous educational websites provide valuable resources, including tutorials, research articles, and interactive content.
The term
catalysis refers to the process by which a
catalyst increases the rate of a chemical reaction without itself undergoing any permanent chemical change. Catalysts work by providing an alternative reaction pathway with a lower activation energy compared to the non-catalyzed mechanism. This means that more reactant molecules have the energy to reach the transition state, thereby increasing the reaction rate.
Types of Catalysts
Catalysts can be broadly classified into
homogeneous and
heterogeneous catalysts. Homogeneous catalysts are present in the same phase as the reactants, usually in a solution. Heterogeneous catalysts exist in a different phase, typically solid catalysts in contact with gaseous or liquid reactants. Additionally, there are
biocatalysts such as enzymes, which are natural catalysts that facilitate biochemical reactions in living organisms.
