However, the practical implementation of this technology faces substantial challenges due to the inherently sluggish kinetics of the anodic oxygen evolution reaction (OER), resulting in compromised hydrogen production efficiency and accelerated catalyst degradation.

However, the high energy consumption of the traditional ammonia synthesis process is inconsistent with the pursuit of “zero carbon,” and there is an urgent need for a new method to synthesize NH<sub>3</sub>. The electrocatalytic NO<sub>3</sub><sup>−</sup>-to-NH<sub>3</sub> (NITRR) offers an ideal route to synthesizing NH<sub>3</sub> under ambient conditions. Nano zero-valent iron (nZVI) has been widely used in nitrate wastewater treatment due to its environmental friendliness, low cost, and high activity. However, nZVI is difficult to recover and prone to deactivation because of its tendency to corrode and agglomerate. Here, we report a method to enhance the activity and stability of nZVI through oxalic acid modification. In this study, oxalic acid and citric acid modified nZVI on foam nickel substrates (OA-nZVI/NF) was examined as examples. Experiments confirmed that the Faraday efficiency of NH<sub>3</sub> (FE<sub>NH3</sub>) from OA-nZVI/NF was 84.9 %, respectively, at −0.4 V vs. RHE, which was significantly higher than that of nZVI/NF (64.5 %). More importantly, the FE<sub>NH3</sub> of OA-nZVI/NF electrod did not decrease significantly after continuous electrolysis for 100 h. Subsequently, electrochemical characterization and control experiments revealed that oxalic acid modification reduced the corrosion potential of nZVI/NF and promoted the generation of hydrogen-free radicals (H*) from nZVI/NF.
