Introduction to Catalysts
Catalysts are substances that increase the rate of a chemical reaction without being consumed in the process. They are crucial in various industrial processes, including the production of chemicals, pharmaceuticals, and environmental applications. What is a New Catalyst?
A new catalyst refers to a recently discovered or developed substance that exhibits improved catalytic properties compared to existing catalysts. These improvements can include increased activity, selectivity, stability, or a combination of these factors.
Why Develop New Catalysts?
The development of new catalysts is driven by the need to enhance efficiency, reduce costs, and minimize environmental impact. For instance, a new catalyst might lower the energy required for a reaction, reduce the formation of unwanted by-products, or enable the use of more sustainable feedstocks.
