Introduction to Catalysis
Catalysis is a branch of chemistry that deals with the acceleration of chemical reactions through the use of catalysts. Catalysts are substances that increase the rate of a chemical reaction without themselves undergoing any permanent chemical change. The discovery of new catalysts is crucial for the development of more efficient and sustainable chemical processes.Why Discover New Catalysts?
The discovery of new catalysts is driven by the need to enhance the efficiency, selectivity, and sustainability of various chemical processes. New catalysts can lead to lower energy consumption, reduced environmental impact, and the development of novel materials and pharmaceuticals. Additionally, new catalysts can help in the conversion of renewable resources into valuable chemicals, thereby promoting a
sustainable economy.
Methods for Discovering New Catalysts
Several methods are employed to discover new catalysts, including: High-throughput screening: This approach involves rapidly testing a large number of catalyst candidates to identify those with the desired activity and selectivity.
Computational modeling: Advances in computational chemistry allow researchers to predict the properties of new catalysts and their potential performance in chemical reactions.
Machine learning and artificial intelligence: These technologies can analyze vast datasets to identify patterns and suggest new catalyst formulations.
