What is Catalysis?
Catalysis is a process in which the rate of a chemical reaction is increased by a substance known as a
catalyst. The catalyst is not consumed in the reaction and can be used repeatedly. Catalysts work by providing an alternative reaction pathway with a lower
activation energy, allowing more molecules to participate in the reaction at a given temperature. This process is crucial in various industrial applications, including the synthesis of
pharmaceuticals,
petrochemicals, and
polymers.
What is Biocatalysis?
Biocatalysis refers to the use of natural catalysts, such as protein enzymes, to perform chemical transformations on organic compounds. Enzymes are highly specific and can operate under mild conditions, making them ideal for
green chemistry applications. Biocatalysis is widely used in the production of
biofuels,
food and beverages, and fine chemicals.
Importance of Catalysis Programs
Catalysis programs are essential for developing new catalysts and improving existing ones to enhance the efficiency and sustainability of chemical processes. These programs often focus on areas such as
heterogeneous catalysis,
homogeneous catalysis, and
enzymatic catalysis. Research in these fields aims to understand the mechanisms of catalytic reactions, design novel catalysts, and apply them in various industrial processes.
