What are the Challenges in Using Metal Oxide Catalysts?
Despite their advantages, metal oxide catalysts face several challenges: - Thermal Stability: Some metal oxides may lose their catalytic properties at high temperatures. - Deactivation: They can be deactivated by poisons or sintering, which reduces their surface area and activity. - Selectivity: Achieving high selectivity for specific reactions can be difficult, necessitating careful tuning of the catalyst's properties.
