Research progress in ceria-based catalysts for the selective catalytic oxidation of NH3
The inadvertent release of ammonia into the atmosphere poses a significant threat to both human health and the environment.To mitigate NH3 slip from industry(stationary source)and vehicle(mobile source)emission control systems,the selective catalytic oxidation of NH3(NH3-SCO)technique has been developed,with catalyst efficiency at its core.Ceria-based materials,renowned for their superior redox capacity,tunable surface states,and facile formation of robust metal-support interactions,are extensively employed in crafting NH3-SCO catalysts.This paper provides a comprehensive synthesis and review of the current research progress in ceria-based NH3-SCO catalysts,offering insights into future development directions.
