There are several types of solid catalysts, including:
1. Heterogeneous Catalysts: These are in a different phase than the reactants. Common examples include metals like platinum and palladium, metal oxides, and zeolites. 2. Supported Catalysts: These involve active catalytic materials dispersed on a support material like silica or alumina to increase surface area and enhance catalytic activity. 3. Mixed Oxides: These are compounds composed of more than one type of metal oxide, often used for complex reactions like those in automotive exhaust treatment.
