Selective Reduction of NO into N₂ Catalyzed by the RhM₂O₃^- Clusters (M = Ta, V, and Al): Importance of the Triatomic Lewis Acid-Base-Acid M^δ+-Rh^δ--M^δ+ Site.

ABSTRACT: Catalytic NO reduction by CO into N₂ and CO₂ is imperative owing to the increasingly rigorous emission regulation. Identifying the nature of active sites that govern the reactivity and selectivity of NO reduction is pivotal to tailor catalysts, while it is extremely challenging because of the complexity of real-life systems. Guided by our newly discovered triatomic Lewis acid-base-acid (LABA, Ce^δ+-Rh^δ--Ce^δ+) site that accounts for the selective reduction of NO into N₂ catalyzed by the RhCe₂O₃^- cluster in gas-phase experiments, the reactivity of the RhM₂O₃^- (M = Ta, V, and Al) clusters in catalytic NO reduction by CO was explored. We determined theoretically th
