Hydrogen energy has garnered significant attention in recent years as a solution to address the global crisis and environmental pollution. While water electrolysis stands out most promising method produce green hydrogen, sluggish reaction kinetics of oxygen evolution (OER) on anode increases cost hydrogen production. One potential this challenge is replace OER with thermodynamically more favorable oxidation small molecules, which can efficiently reduce while simultaneously yielding high-value chemicals. Up now, various organic reactions have been reported couple evolution, including alcohol oxidation, biomass platform molecule upgrading, sacrificial reagents associated wastewater treatments. This review concentrates advancements mechanism, catalyst, reactor, process field, discussion its prospects for commercialization.

Synchronous electrosynthesis of value-added adipic acid (AA) and H2 is extremely crucial for carbon neutrality. However, accomplishing the preparation AA at large current density with high selectivity still challenging. Herein, a robust Mo-doped Ni2P@Ni12P5 heterojunction more P vacancies on Ni foam proposed simultaneous electrooxidation cyclohexanol (CHAOR) to hydrogen evolution reaction (HER) density. Combined X-ray photoelectron spectroscopy, absorption fine structure, electron spin resonance confirm that Mo incorporation induces charge redistribution Ni2P@Ni12P5, where adjusts electrons from P, triggers vacancies. Further experimental theoretical investigations reveal d-band center upshifted, optimizing adsorption energies water electron-rich site boosting HER activity. Besides, Ni3+ generated electron-deficient induced by Mo, alongside OH* triggered concurrently promote CHA dehydrogenation C─C bond cleavage, decreasing energy barrier CHAOR. Consequently, two-electrode flow electrolyzer achieves industrial (>230 mA cm-2) 85.7% yield, 100% Faradaic efficiency production. This study showcases an bifunctional electrocatalyst production productivity.

The low-potential aldehyde oxidation reaction can occur at low potential (~0 VRHE) and release H2 the anode, enabling hydrogen production with less than one-tenth of energy consumption required for water splitting. Nevertheless, activity stability Cu catalysts remain inadequate due to oxidative deactivation Cu-based materials. Herein, we elucidate reactivation cycle electrocatalyst develop a self-reactivating PdCu catalyst that exhibits significantly enhanced stability. Initially, in-situ Raman spectroscopy confirm involved in electrochemical non-electrochemical reduction. Subsequently, X-ray absorption fine structure reveal Pd component accelerates rate reduction, thereby enhancing electrocatalyst. Finally, bipolar device is assembled utilizing electrocatalyst, which deliver current 400 mA cm−2 0.42 V operate continuously 120 h. This work offers guidance enhance system. A dual-side system more efficient splitting but suffers from issues. Here, authors report operates stably h, offering an alternative solution energy-efficient production.

Abstract Coupled electrolyzer is a desirable way to realize efficient energy conversion from electricity chemical energy. Using coupled electrolyzers highly valuable chemicals (e.g., H 2 , CH x COO − nitrile, S, NH 3 CO) can be obtained at low voltages, environmental pollutants alleviated, and wastewater ammonia, urea, hydrazine) recycled. They are even helpful the goal of carbon peaking neutrality. Compared traditional methods, small molecule‐based more cost‐efficient. This review summarizes state‐of‐art electrolyzers, mainly replacement oxygen reduction reaction with oxidation reactions molecules their further coupling cathodic such as hydrogen evolution (HER), (ORR), CO (CO RR), N (NRR), other matching molecules. In terms molecules, two types covered: sacrificial agent (SAOR) electrochemical synthesis (ESR). After detailing design principle several construction, characterization, performance systematically overviewed along discussion outline current challenges prospects this appealing strategy.
