Abstract Exploring an efficient nonnoble metal catalyst for hydrogen evolution reaction (HER) is critical industrial alkaline water electrolysis. However, it remains a great challenge due to the additional energy required H─OH bond cleavage and lack of enough H 2 O adsorption sites most catalysts. Herein, integration oxophilic Eu 3 with NiCo alloy evoked multisite synergism facilitate dissociation HER proposed. The optimized ‐NiCo exhibits excellent activity low overpotential only 60 mV at 10 mA cm −2 good electrochemical stability, which superior that ‐free comparable benchmark Pt/C. key roles on enhanced performance are identified by in situ Raman spectroscopy theoretical calculations. It discovered strong oxophilicity facilitates breakage bonding while evoking electron redistribution /NiCo interface accelerating Volmer step HER. Furthermore, obtained as both anode cathode displays overall water‐splitting stability 1.0 M KOH solution. believed this study provides important inspiration design high‐performance electrocatalysts toward based rare‐earth materials.

Electrochemical H2 production from water favors low-voltage molecular oxidation to replace the oxygen evolution reaction as an energy-saving and value-added approach. However, there exists a mismatch between high demand for slow anodic reactions, restricting practical applications of such hybrid systems. Here, we propose bipolar approach, with generation N–N oxidatively coupled dehydrogenation (OCD) 3,5-diamino-1H-1,2,4-triazole (DAT), in addition cathodic generation. The system requires relatively low potentials 0.872 1.108 V vs RHE reach 10 500 mA cm–2, respectively. H-type electrolyzer only 0.946 1.129 deliver 100 respectively, electricity consumption (1.3 kWh per m3 H2) reduced by 68%, compared conventional splitting. Moreover, process is highly appealing due absence traditional hazardous synthetic conditions azo compounds at anode crossover/mixing H2/O2 electrolyzer. A flow-type operates stably cm–2 300 h. Mechanistic studies reveal that Pt single atom nanoparticle (Pt1,n) optimize adsorption S active sites over Pt1,n@VS2 catalysts. At anode, stepwise −NH2 DAT then oxidative coupling −N–N– predominantly form while generating H2. present report paves new way atom-economical aminotriazole green electrosynthesis chemicals.

The development of cost-effective and efficient electrocatalysts for the hydrogen evolution reaction (HER) is critical to advancing green production technologies. Here, we present a plasmonic tungsten oxide (W18O49) material integrated with ultralow platinum (Pt) loadings (0.4, 0.8, 1.6 wt %) that delivers high HER performances under both dark visible light conditions. 0.4 % Pt–W18O49 catalyst exhibits remarkable mass activity, outperforming commercial Pt/C by factors 15 30 740 nm LED illumination, respectively. Density functional theory (DFT) calculations reveal synergy between Pt plasmonically active W18O49 optimizes charge transfer adsorption, resulting in lowered energy barriers kinetics. Furthermore, excitation enhances catalytic activity facilitating electron transfer. This work introduces scalable, strategy combining earth-abundant materials minimal usage, providing pathway toward high-efficiency catalysts. These findings highlight potential plasmonic-catalyst integration
