Several materials are known for their redox properties and are widely used in catalysis:
Transition Metals: Metals like platinum (Pt), palladium (Pd), and ruthenium (Ru) are known for their excellent redox properties. Metal Oxides: Oxides of metals such as titanium (TiO2), cerium (CeO2), and vanadium (V2O5) are widely used as redox-active catalysts. Perovskites: These materials have a flexible structure that allows for a wide range of oxidation states, making them versatile catalysts.
