H2 production via water electrolysis is of great significance in clean energy production, which, however, suffers from the sluggish kinetics of the anodic oxygen evolution reaction (OER). Moreover, the anode product, O2, which is of rather low value, may lead to dangerous explosions and the generation of membrane‐degrading reactive oxygen species. Herein, to address these issues of electrocatalytic H2 production, we summarize the most recent advances in three stages based on the benefit increments and various electron donation routes, which are: 1) electron donation by traditional OER: developing efficient catalysts for water oxidation to promote H2 production; 2) electron donation by the oxidation of sacrificial agents: using sacrificial agents to assist H2 production; 3) electron donation by electrosynthesis reaction: achieving electrosynthesis in parallel with cathodic H2 production. Present challenges and related prospects will also be discussed, hopefully to benefit the further progress of electrocatalytic H2 generation.

“…For bifunctional Co-Ni alloy electrocatalyst, the Ni and/or Co metals have more superior catalytic activity toward HER, while the oxidized species such as NiO, CoO, or Co-NiO play a vital role in GOR (Figure 5c,d). [74] In consequence, whether they are completely different electrodes, the same precursor electrodes, or fully identical electrodes, it is an attractive alternative for replacing OER with GOR for enhancing H 2 production.…”

Affected by both the energy shortage and environmental crisis, the development of electrocatalytic conversion process powered by renewable energy (wind, solar, tide, etc.) has received considerable attention. [1][2][3][4][5] Generally, electrocatalytic reactions involve To make efficient use of electrical energy in the whole electrocatalysis conversion process, the integrating of anode and cathode reactions plays a vital role. The combination of electrocatalytic anodic oxidation with cathodic reduction can not only maximize the return of energy investment, but also produces value-added materials on both sides. Herein, in this review, recent advances in co-electrolysis processes for valuable chemical production are systematically summarized. To be more specific, the popular hydrogen evolution reaction, carbon dioxide reduction reaction, nitrogen reduction reaction as well as nitrate reduction reaction integrated with anodic oxidation reactions to valueadded products, respectively are comprehensively reviewed, and then other paired electrolysis systems (especially for biomass-based compounds) toward high-value-added chemical generation are discussed in detail. This review sheds light on the integration of electrocatalytic reductions and oxidation reactions to develop high-value substances. To benefit researchers and facilitate the progress in this field, the challenges and future prospects for these integrated reactions are also proposed.

Die elektrokatalytische Wasserspaltung gilt als die nachhaltigste und sauberste Technologie zur Produktion von H 2 . Leider wird die Effizienz durch die träge Kinetik der Sauerstoffentwicklungsreaktion (OER) an der Anode stark eingeschränkt. Im Gegensatz zur OER ist die Elektrooxidation organischer Stoffe (EOO) thermodynamisch und kinetisch günstiger. Daher hat sich die Kopplung der EOO mit der Wasserstoffentwicklungsreaktion (HER) als Alternative herauskristallisiert, weil dabei die katalytische Effizienz für die H 2 -Produktion erheblich verbessert werden kann. Gleichzeitig können hochwertige organische Verbindungen an der Anode durch Verbesserung der Elektrooxidation erzeugt werden. In diesem Kurzaufsatz werden die aktuellsten Fortschritte und Meilensteine, die bereits bei der Kopplung der EOO mit der HER erzielt wurden, vorgestellt. Der Fokus liegt auf dem Design des Anodenkatalysators, dem Verständnis des Reaktionsmechanismus und der Konstruktion des Elektrolyseurs. Darüber hinaus werden Herausforderungen und Perspektiven in Bezug auf die künftige Entwicklung dieser innovativen Technologie aufgezeigt.
