A catalyst is a substance that accelerates the rate of a chemical reaction and not consumed during the reaction traditional catalysis can be classified into homogeneous catalysis and heterogeneous catalysis in a homogeneous catalytic reaction, the catalyst and reactants are in the same phase, generally occurring in a liquid state. Catalysis which involves the use of a catalyst in a different phase from the reactants is known as heterogeneous catalysis catalysts are known to enhance rates of reaction without being consumed and they also reduce activation energies.
