  • Catalysis - Wikipedia
    Catalysts generally react with one or more reactants to form intermediates that subsequently give the final reaction product, in the process of regenerating the catalyst
  • Catalyst | Examples, Definition, Facts | Britannica
    Catalyst, in chemistry, any substance that increases the rate of a reaction without itself being consumed Enzymes are naturally occurring catalysts responsible for many essential biochemical reactions In general, catalytic action is a chemical reaction between the catalyst and a reactant
