In Situ Construction of Cu⁺-O_v-Ce³⁺ Sites on CeO₂ for Efficient NH₃ Oxidation.

ABSTRACT: Ammonia (NH₃) emissions adversely affect both the environment and human health. The selective catalytic oxidation of NH₃ (NH₃-SCO) holds great promise for NH₃ abatement; however, there remains a lack of cost-effective NH₃-SCO catalysts with high activity and N₂ selectivity for practical applications. This study reports on a strategy for constructing an outstanding NH₃ oxidation catalyst via the in situ doping of Cu into CeO₂ nanorods. The designed CeCuO_x nanorod catalyst shows remarkable activity, N₂ selectivity, and stability for NH₃ oxidation, achieving complete conversion below 250 °C, with ≈80% N₂ selectivity. The results of various characterization tests
