Abstract

Here, we present the development of an efficient Pt/CeO₂ catalyst for electrocatalytic N₂ oxidation to nitrate. Characterization results indicate that highly dispersed Pt and oxygen vacancies from CeO₂ nanocubes (NCs) exhibit strong interactions, which promote the N₂ adsorption on the catalyst surface and suppress the competitive OER activity on oxygen vacancies, resulting in significantly enhanced e-NOR performance.
