What is Catalysis?
Catalysis refers to the process by which the rate of a chemical reaction is increased by a substance called a
catalyst. The catalyst itself is not consumed in the reaction and can be used repeatedly. Catalysts are crucial in various industrial processes, influencing the production of chemicals, pharmaceuticals, and even fuels.
Why is Innovation in Catalysis Important?
Innovation in catalysis is essential for improving efficiency, reducing costs, and minimizing environmental impact. The development of new catalysts can lead to advancements in
green chemistry, allowing for more sustainable manufacturing processes. Moreover, innovative catalytic processes can help address global challenges such as climate change and energy shortages.
