High single-pass conversion of nitrous oxide to dinitrogen in gas-diffusion-electrolyzer.

ABSTRACT: Electrocatalytic N₂O reduction reaction offers a sustainable solution of converting greenhouse gas N₂O to N₂ under ambient conditions, but achieving high single-pass conversion remains challenging. Here, we present a gas-diffusion-electrolyzer system with copper-silver bimetallic nanoalloy serving as the catalyst for efficient N₂O reduction, realizing a single-pass conversion rate of 79.4% and a decomposition rate of 1381.7 μmol h^-1 mg_cat^-1 for 10 vol.% N₂O. Computational fluid dynamics simulation shows that the system optimizes gas flow regime and reduces diffusion distance compared to batch system, ensuring a uniform N₂O distribution over cathode surface. The combination of Ag with Cu syner
