What Types of Catalysts are Used in Water Treatment?
Several types of catalysts are utilized in water treatment processes, including homogeneous catalysts and heterogeneous catalysts. Homogeneous catalysts are in the same phase as the reactants, usually dissolved in water, while heterogeneous catalysts are in a different phase, typically solid materials that pollutants adhere to. Common materials used as heterogeneous catalysts include activated carbon, titanium dioxide, and various metal oxides.
