What is Homogeneous Catalyst?
A homogeneous catalyst is a catalyst that exists in the same phase as the reactants, most commonly in solution. Because catalyst and reactants are intimately mixed, homogeneous catalysts often provide high selectivity and activity. Examples include acid-catalysed esterification in solution and transition metal complexes used in industrial hydroformylation reactions.
