Electrocatalysis provides a desirable approach for moving toward sustainable energy future. Herein, rapid and facile potential pulse method was implemented one-pot electrosynthesis of the amorphous Ni-Co-Fe-P (NCFP) electrocatalyst. The 2 mg cm-2 loaded electrode displayed excellent trifunctional electrocatalytic activities hydrogen evolution reaction (η HER j=10 = 102 mV), oxygen OER 250 reduction (E ORR 1/2 0.73 V) in alkaline solutions. Interestingly, even lower overpotential η 86 mV obtained at super-high mass loading 18.7 cm-2, demonstrating its feasibility industrial-level applications. NCFP electrocatalyst also offered superior catalytic activity seawater electrolysis industrially required current rates (500 mA cm-2). When as an air cathode catalyst aqueous quasi-solid state zinc-air battery, both devices delivered performance. This study insights into transformative technology towards

Abstract The electrocatalytic oxidation of benzyl alcohol (BAOR) is crucial for promoting green industrial processes and enhancing the yield productivity high‐value chemicals. However, there are challenges in this field, such as difficult steps alkaline electrolytes, slow reaction kinetics, difficulty preserving activity catalysts during long‐term catalytic reactions. Addressing these issues achieving synergistic reactions to improve energy utilization by combining hydrogen evolution with enhanced catalyst stability warrants focused investigation. Herein, study reports a Co 3 Ni 6 S 8 ‐based catalyst, 0.33 0.67 1 ‐10c, which can achieve (BA) solution over 350 h, conversion rate BA exceeding 90% Faraday efficiency benzoic acid (BAA) 99%. production capacity ‐10c also evaluated both three‐electrode dual‐electrode systems. In system, factor 9.59 compared absence BA, while increased 7.85. This work presents highly efficient durable its integration production.

Abstract Coupling electro‐refinery with water electrolysis paves a sustainable pathway for parallel production of value‐added chemicals and hydrogen. However, its practical feasibility remains hindered by large overpotentials, unsatisfactory selectivity, inadequate durability. Here, we report pH‐asymmetric hybrid system (AHSE) to realize ampere‐level, long‐term alcohols hydrogen production. By harnessing internal neutralization energy, the AHSE simultaneously produces benzoic acid (Ph‐COOH) at low electricity expense 3.19–3.78 kWh per m 3 H 2 500 mA cm −2 , saving 24.6–30.6% energy than pH‐symmetric systems. The operational stability is maximized independent optimization pH conditions anode cathode, allowing continuous operation over 4100 h current densities 500–1000 . High Faradaic efficiency (FE) 91.3–97.7% reached benzyl alcohol (BA) conversion, 78.5–95.5% Ph‐COOH selectivity. When scaled up 100 folds, retains 85% FE BA conversion 88.5% selectivity while yielding fast rate 18.7 L −1 an ultra‐high 50 A 3.14 V.
