Alkaline water (H2O) electrolysis is currently a commercialized green hydrogen (H2) production technology, yet the unsatisfactory evolution reaction (HER) performance severely limits its energy conversion efficiency and cost reduction. Herein, PtRu2.9Fe0.15Co1.5Ni1.3 high entropy alloys (HEAs) synthesized subsequently exploited electrochemically induced structural oxidation processes to construct self-reconfigurable HEAs, as an efficient alkaline HER catalyst. The optimized self-reconstructed HEAs with cobalt rutheniate interface (HEAs-Co2RuO4) exhibits excellent performance, requiring just 11.8 mV obtain current density (j) of 10 mA cm-2 in 1 m KOH. And j on HEAs-Co2RuO4 41.8 at 0.07 VRHE, 2.0 6.1 times higher than 20% Pt/C. Mechanism studies reveal that improved due formation HEAs-Co2RuO4, which significantly shrinks Helmholtz layer, provides new fast material transport channel, boosts H2O adsorption, reduces thus accelerates HER. This research not only throws light self-reconstruction catalysts but also guidance for rational design electrocatalysts.

Abstract Transition metal‐catalyzed transfer hydrogenation (TH) with in situ negative hydrogen (H − ) has received extensive attention as an alternative to conventional high‐pressure processes. However, the insufficient activity of production and unclear conversion process remain a great challenge. In this work, brand new bimetallic ternary‐structured catalysts (Ru 1+n M 1 ‐TiO 2 , M=Co, Cu, Fe, Ni) were synthesized efficiently generate H donors from ammonia borane (AB, NH 3 BH for nitrobenzene under moderate conditions. The Ru Co exhibited highest form AB hydrolysis TOF value 2716 min −1 . achieved >90 % yields within 3–4 hours converting anilines using AB. Mechanistic studies revealed that high was due SA sites bimetallic‐ternary‐structured catalyst required lowest energy activation O, respectively. Remarkably, clusters obvious synergistic effect TH process, which promoted tandem nitroaromatics. This work demonstrated efficient approach donor further provided inspiration on development multifunctional catalysts.

The utilization of hydrogen in safety conditions is crucial for the development a hydrogen-based economy. Among all methodologies, solid-state release from ammonia borane through thermal stimuli very promising due to high theoretical release. Generally, carbonaceous or inorganic matrices have been used tune reactivity borane. Nevertheless, these solutions lack chemical tunability, and they do not allow one properly complex pathway In this study, we investigated effect bioderived multifunctional polymeric matrix on borane, reaching pure 1.2 wt.% at 94 °C. We also describe new pathways involving formation anchored intermediates, namely BxNy species.
