The catalytic properties of perovskite oxides can be finely tuned by altering the composition of the A and B sites. For example:
- A-Site Substitution: Changing the A-site cation can affect the lattice parameters, oxygen vacancies, and overall stability of the material. - B-Site Substitution: Varying the B-site cation can modify the electronic structure, affecting the material's ability to adsorb and activate reactants. - Oxygen Vacancies: Introduction of oxygen vacancies can enhance ionic conductivity and surface reactivity.
