Abstract Due to the competitive relationship between nitrate reduction reaction (NO 3 − RR) and hydrogen evolution (HER), conventional approach improve Faradaic efficiency is select a catalyst without HER activity. Nevertheless, such strategy not only limits application of catalysts in NO RR, but also causes insufficient source, thereby sacrificing ammonia yield rate. We believe that should be excluded from hydrogenation reduction. Herein, taking traditional water electrolysis material Co O 4 as model system, we reveal oxygen vacancies on crystal facet can greatly promote dissociation capture intermediate for successfully shifting pathway hydrogenation. Beyond development, construct hybrid reactor achieve an recovery rate 1216.8 g‐N m −2 d −1 nuclear industry wastewater with ultra‐high concentration. This study breaks through limitation which provides significant insight into designing mechanism.
