Perovskite structures are a type of crystalline structure characterized by the general formula ABX3. In this structure, 'A' and 'B' are cations of different sizes, and 'X' is an anion, typically oxygen. The most common type of perovskite is calcium titanate (CaTiO3), but numerous other compositions exist. These structures are renowned for their versatility and have been extensively studied for various applications, including catalysis.
