What Types of Catalysts Are Used for Emission Control?
Several types of catalysts are employed for emission control, including:
Heterogeneous catalysts: These are solid catalysts that facilitate reactions in a different phase than the reactants. Examples include platinum and palladium used in catalytic converters. Homogeneous catalysts: These catalysts operate in the same phase as the reactants, often used in liquid-phase reactions. Biocatalysts: Enzymes that can catalyze reactions in biological systems, useful in treating wastewater emissions.
