Abstract Electrochemical nitrite reduction reaction (NO 2 RR) has emerged as a promising alternative approach for ammonia (NH 3 ) production, offering both energy efficiency and environmental sustainability. The rational regulation of active hydrogen (*H) is pivotal NO − ‐to‐NH conversion, yet it remains significant challenge in the context RR. In this study, molybdenum boride (MBene) multilayers are introduced an electronic support to integrate with palladium (Pd) nanoparticles, creating dual catalytic sites that effectively balance adsorption *H *NO , thereby enabling synergistic catalysis Theoretical experimental analyses revealed efficiently generated on Pd subsequently undergoes spillover ‐adsorbed MBene surfaces, facilitating accelerated hydrogenation NH synthesis. Consequently, Pd/MBene catalyst demonstrated exceptional performance, achieving high Faradaic 89%, yield rate 16.9 mg h −1 cat remarkable cycling stability at low applied potential ‐0.3 V versus RHE. Motivated by outstanding RR further utilized cathode construct Zn‐nitrite formaldehyde‐nitrite batteries. These systems functionality simultaneous production electricity generation, highlighting versatile efficient sustainable conversion.
