Oxides are significant in catalysis because of their ability to facilitate various chemical reactions. Their importance stems from several factors: 1. Surface Area: Many oxides have high surface areas, which provide more active sites for reactions to occur. 2. Thermal Stability: Oxides are generally thermally stable, making them suitable for reactions that require high temperatures. 3. Acid-Base Properties: Oxides can exhibit both acidic and basic properties, allowing them to catalyze a wide range of reactions. 4. Electronic Properties: The electronic configurations of oxides can be tuned to enhance catalytic activity.
