Nitrogen reduction reaction (NRR) offers a sustainable alternative to the energy-intensive Haber–Bosch process for ammonia synthesis under ambient conditions while also mitigating serious global warming impact of fossil fuels. However, competing hydrogen evolution remains significant challenge in NRR systems. In this work, we propose Bi-doped CuFe nanoclusters loaded on 3D copper foams (CFs) as an enhanced N2 electrocatalyst NRR. The catalyst exhibited superior activity compared undoped counterpart, achieving high yield 216.1 μg h–1 cm–2 with Faradaic efficiency 46.8% at −0.4 V vs reversible electrode. Importantly, showed good selectivity minimal N2H4 byproduct generation and excellent stability. Bismuth incorporation induced lattice expansion electronic defects, which turn created structural defects oxygen vacancies. These changes effectively promoted adsorption activation molecules. Comprehensive characterization revealed that Bi doping decreased vacancy density bulk phase but increased surface. This phenomenon expanded spacing, inhibiting H* combination produce H2, surface vacancies regulated strength NxHy intermediates during electrocatalytic process. Density functional theory calculations further confirmed active sites, well subsequent hydrogenation steps, leading lower energy barrier distal pathway NH3 formation. Moreover, Zn–N2 battery assembled Bi–CuFe/CF shows power 14.01 mW cm–2, enables simultaneous production supply, gives it potential field energy. work demonstrates promising approach developing efficient electrocatalysts by structure modulation, contributing transition toward low-carbon economy.
