The nitrate (NO3−) electroreduction into ammonia (NH3) represents a promising approach for sustainable NH3 synthesis. However, the variation of adsorption configurations renders great difficulties in the simultaneous optimization of binding energy for the intermediates. Though the extensively reported Cu-based electrocatalysts benefit NO3− adsorption, one of the key issues lies in the accumulation of nitrite (NO2−) due to its weak adsorption, resulting in the rapid deactivation of catalysts and sluggish kinetics of subsequent hydrogenation steps. Here we report a tandem electrocatalyst by combining Cu single atoms catalysts with adjacent Co3O4 nanosheets to boost the electroreduction of NO3− to NH3. The obtained tandem catalyst exhibits a yield rate for NH3 of 114.0 mg $${}_{{{{{{\rm{NH}}}}}}_3}$$ NH 3 h−1 cm−2, which exceeds the previous values for the reported Cu-based catalysts. Mechanism investigations unveil that the combination of Co3O4 regulates the adsorption configuration of NO2− and strengthens the binding with NO2−, thus accelerating the electroreduction of NO3− to NH3.
