Catalysts can be classified into several types, such as homogeneous, heterogeneous, and enzymatic catalysts. Homogeneous catalysts operate in the same phase as the reactants, while heterogeneous catalysts function in a different phase. Enzymatic catalysts, or enzymes, are biological molecules that catalyze biochemical reactions. Common examples include platinum in automotive catalytic converters and amylase in the digestion of carbohydrates.
