In general catalysts are described as substances capable of speeding up a chemical reaction, but there are some reactions that do not proceed at all unless a catalyst is present. These reactions may be thermodynamically feasible but their kinetics are so unfavourable that no reaction occurs. For chemical reactions to … See more Heterogeneous catalysts are solids that catalyse the reactions between liquid or gaseous reactants. (Note that the reaction itself usually occurs at the surface of the catalyst.) The catalytically active solid is typically coated onto … See more Today, the industrial world relies upon an enormous number of chemical reactions and an even greater number of catalysts.
