Define homogeneous catalyst
WebMar 4, 2024 · Catalysis is defined as increasing the rate of a chemical reaction by introducing a catalyst. A catalyst, in turn, is a substance that is not consumed by the chemical reaction, but acts to lower its activation energy. In other words, a catalyst is both a reactant and product of a chemical reaction. Typically, only a very small quantity of ... WebBiocatalysis. Three dimensional structure of an enzyme. Biocatalysis utilizes these biological macromolecules to catalyze small molecule transformations. Biocatalysis refers to the use of living (biological) systems or their parts to speed up ( catalyze) chemical reactions. In biocatalytic processes, natural catalysts, such as enzymes, perform ...

In chemistry, homogeneous catalysis is catalysis by a soluble catalyst in a solution. Homogeneous catalysis refers to reactions where the catalyst is in the same phase as the reactants, principally in solution. In contrast, heterogeneous catalysis describes processes where the catalysts and substrate are in distinct phases, typically solid-gas, respectively. The term is used almost exclusively to describe solutions and implies catalysis by organometallic compounds.
