What Are Some Examples of Catalysts That Utilize Interstitials?
Several catalysts utilize interstitials to improve their performance:
1. Titanium Dioxide (TiO2): Nitrogen-doped TiO2 can have interstitial nitrogen atoms, enhancing its photocatalytic activity under visible light.
2. Palladium (Pd): Palladium hydride (PdHx) contains interstitial hydrogen, making it highly effective for hydrogenation reactions.
3. Ceria (CeO2): Cerium oxide can have interstitial oxygen ions, which enhance its ability to undergo redox cycles, making it useful in oxidation reactions and as a support for other catalysts.
