Accelerating Nitrite Reduction to Ammonia: The Synergistic Effect of Dual Active Site Pt-Ir Catalysts
{{output}}
Ir-based catalysts have been demonstrated as promising catalysts for the reduction of NO2- to ammonia (NRA). However, the strong competitive adsorption of NO2- over H2 on Ir sites, leading to H* deficiency at high NO2- concentrations, would hinder its real app... ...
