What are 3 types of catalyst?

Catalysts and their associated catalytic reactions come in three main types: homogeneous catalysts, heterogeneous catalysts and biocatalysts (usually called enzymes). Less common but still important types of catalyst activities include photocatalysis, environmental catalysis and green catalytic processes.
