Abstract Ammonia electrolysis represents a green and economical strategy for hydrogen production, yet the progress is hindered by lack of efficient catalyst to boost kinetically sluggish ammonia oxidation reaction (AOR). Herein, ternary PtCoSn/C prepared facile wet‐chemical reduction method applied AOR, which exhibits specific activity 0.87 mA cm ECSA −2 , 3 times that Pt/C. The highly enhanced derived from regulated intermediates adsorption on surface, evidenced in situ attenuated total reflection Fourier transform infrared measurements. co‐alloying Co Sn with Pt not only contributes weakened binding strength *OH *H species enhancing NH related intermediates, but also facilitates supply OH − sites, compensating fast consumption double layer during AOR. Benefiting its high evolution reaction, can be used as bifunctional two‐electrode system, requires 0.78 V drive current density 10 . This work sheds light developing AOR catalysts, promoting production electrolysis.
