Vacancies are crucial because they can significantly alter the electronic and structural properties of the catalyst, making them more reactive. Here are some reasons why vacancies are important:
Enhanced Adsorption: Vacancies can provide additional sites for the adsorption of reactant molecules, increasing the surface area available for reaction. Improved Reactivity: The absence of atoms can create unsaturated bonds, which can be highly reactive and facilitate bond-breaking and bond-forming processes. Charge Transfer: Vacancies can facilitate the transfer of charge between the catalyst and the reactants, which is essential in redox reactions.
