Abstract Electrocatalytic nitrate reduction reaction (NO 3 RR) toward ammonia synthesis is recognized as a sustainable strategy to balance the global nitrogen cycle. However, it still remains great challenge achieve highly efficient production due complex proton‐coupled electron transfer process in NO RR. Here, controlled of RuMo alloy nanoflowers (NFs) with unconventional face‐centered cubic (fcc) phase and hexagonal close‐packed/fcc heterophase for RR reported. Significantly, fcc NFs demonstrate high Faradaic efficiency 95.2% large yield rate 32.7 mg h −1 cat at 0 −0.1 V (vs reversible hydrogen electrode), respectively. In situ characterizations theoretical calculations have unraveled that possess highest d‐band center superior electroactivity, which originates from strong Ru─Mo interactions intrinsic activity phase. The optimal electronic structures supply adsorption key intermediates suppression competitive evolution, further determines remarkable performance. successful demonstration high‐performance zinc‐nitrate batteries suggests their substantial application potential electrochemical energy systems.

Abstract Electrocatalytic C‐N coupling reaction is regarded as a promising strategy for achieving clean and sustainable urea production by coreducing CO 2 nitrogen species, thus contributing to carbon neutrality the artificial cycle. However, restricted sluggish adsorption of reactants, competitive side reactions, multistep pathways, electrochemical suffers from low yield rate selectivity so far. In order comprehensively improve synthesis performance, it crucial develop highly efficient catalysts coupling. this article, catalyst‐designing strategies, mechanisms, fundamental research methods are reviewed. For coreduction different several prevailing mechanisms discussed. With aim establishing standard system, fundamentals electrocatalytic introduced. The most important strategies boosting discussed, including heteroatom doping, vacancy engineering, crystal facet regulation, atom‐scale modulation, alloying heterostructure construction. Finally, challenges perspectives proposed future industrial applications

Abstract Tandem nitrate electroreduction reaction (NO 3 − RR) is a promising method for green ammonia (NH ) synthesis. However, the mismatched kinetics processes between NO ‐to‐NO 2 and ‐to‐NH results in poor selectivity NH excess evolution electrolyte solution. Herein, Ni 2+ substitution strategy developing oxide heterostructure Co/Fe layered double oxides (LDOs) was designed employed as tandem electrocataltysts RR. (Co 0.83 0.16 Fe exhibited high yield rate of 50.4 mg ⋅ cm −2 h −1 with Faradaic efficiency 97.8 % at −0.42 V vs. reversible hydrogen electrode (RHE) pulsed electrolysis test. By combining situ / operando characterization technologies theoretical calculations, we observed strong over Fe, playing dual role RR by i) modifying electronic behavior Co, ii) serving complementary site active (*H) supply. Therefore, adsorption capacity *NO its subsequent hydrogenation on Co sites became more thermodynamically feasible. This study shows that promotes provides insights into design electrocatalysts evolution.

Abstract Electrochemical reduction of nitrate to ammonia (NO 3 RR) is a promising and eco‐friendly strategy for production. However, the sluggish kinetics eight‐electron transfer process poor mechanistic understanding strongly impedes its application. To unveil internal laws, herein, library Pd‐based bimetallene with various transition metal dopants (PdM (M=Fe, Co, Ni, Cu)) are screened learn their structure–activity relationship towards NO RR. The ultra‐thin structure metallene greatly facilitates exposure active sites, metals break electronic balance upshift d‐band center, thus optimizing intermediates adsorption. anisotropic characteristics these make RR activity in order PdCu>PdCo≈PdFe>PdNi>Pd, record‐high NH yield rate 295 mg h −1 cat along Faradaic efficiency 90.9 % achieved neutral electrolyte on PdCu bimetallene. Detailed studies further reveal that moderate N‐species (*NO *NO 2 ) adsorption ability, enhanced activation, reduced HER facilitate We believe our results will give systematic guidance future design catalysts.
