Abstract
Abstract Electrocatalytic hydrogen peroxide (H 2 O 2 ) synthesis via the two‐electron oxygen reduction reaction (2e ORR) pathway is becoming increasingly important due to the green production process. Here, cationic vacancies on nickel phosphide, as a proof‐of‐concept to regulate the catalyst's physicochemical properties, are introduced for efficient H 2 O 2 electrosynthesis. The as‐fabricated Ni cationic vacancies (V Ni )‐enriched Ni 2− x P‐V Ni electrocatalyst exhibits remarkable 2e ORR performance with H 2 O 2 molar fraction of >95% and Faradaic efficiencies of >90% in all pH conditions under a wide range of applied potentials. Impressively, the as‐created V Ni possesses superb long‐term durability…
