Catalysis can be broadly categorized into three types: homogeneous catalysis, heterogeneous catalysis, and biocatalysis. Homogeneous catalysis involves catalysts in the same phase as the reactants, typically in solution. Heterogeneous catalysis uses catalysts in a different phase, often solids interacting with gases or liquids. Biocatalysis employs natural catalysts, such as enzymes, to drive chemical reactions.
