What are the Key Properties of Perovskites that Enhance Catalytic Activity?
Several properties of perovskites make them excellent materials for catalysis:
High Thermal Stability: Perovskites can withstand high temperatures, making them suitable for reactions requiring thermal endurance. Oxygen Vacancies: These defects in the crystal structure can enhance catalytic activity by providing additional active sites. Mixed Oxidation States: The ability to host multiple oxidation states allows perovskites to participate in redox reactions effectively. Tunability: By substituting different elements at the A or B sites, the electronic and structural properties can be precisely controlled.
