Designing efficient and cost-effective electrocatalysts is crucial for the large-scale development of sustainable hydrogen energy. Amorphous catalysts hold great promise application due to their structural flexibility high exposure active sites. We report a novel method in situ growth amorphous CoNiRuOx nanoparticle structures (CoNiRuOx/NF) on nickel foam substrate. In 1 m KOH, CoNiRuOx/NF achieves current density 10 mA/cm2 with evolution reaction (HER) overpotential only 43 mV remains stable over 100 h at mA/cm2. An alkaline electrolyzer assembled as cathode delivers 2.97 times higher than that an IrO2||Pt/C electrode pair potential 2 V exhibits excellent long-term durability exceeding h. Experimental results reveal combined replacement corrosion reactions facilitate formation structure. This work provides valuable insights developing scalable catalysts.

Heterostructure‐Derived Heterovalent Fe(OH)₂/Fe Pair Sites: Tuning Adsorption of Intermediates and Enhancing Utilization of Atomic ^*H for Efficient Nitrate Reduction to Ammonia

Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Март 5, 2025

Abstract Electrocatalytic nitrate reduction (NO3RR) to valued ammonia is an ideal supplementary route the Haber–Bosch method and a strategy for removal utilization of pollutants. However, due fact that NO3RR goes through complicated multi‐electron/proton transfer, catalysts with monovalent metal sites are difficult tackle multitasking it involves, leading unsatisfactory conversion efficiency selectivity. Herein, heterovalent Fe(OH) 2 /Fe pair supported onto carbon nanotubes (Fe(OH) /Fe@CNTs) presented via electrochemical reconstruction CNTs‐supporting FeS/Fe C heterostructure. /Fe@CNTs exhibits high NH 3 yield rate 0.67 mmol h −1 cm −2 FE 95.1% at −0.4 V versus RHE, which mainly attributed regulated electronic structure cooperation iron sites. Meanwhile, adsorption nitrogen‐containing species adjusted * H enhanced. Moreover, balanced content Fe creates “buffering effect” maintain its activity stability. Theoretical calculations combined in situ FTIR Raman spectra reveal novel multiple reaction pathway on sites, entirely different from single or . Clearly, this study offers creative design advanced multivalent
