Green hydrogen from electrolysis of water has attracted widespread attention as a renewable power source. Among several production methods, it become the most promising technology. However, there is no large-scale system currently that can compete with conventional fossil fuel production. Renewable energy electrocatalytic splitting an ideal technology environmental cleanliness protection and good purity, which meet requirements future development. This review summarizes introduces current status by three aspects: electricity, catalyst electrolyte. In particular, present situation latest progress key sources power, catalytic materials electrolyzers for are introduced. Finally, problems generation electrolytic directions next-generation green in discussed outlooked. It expected this will have important impact on field water.

The utilization of renewable energy for hydrogen production presents a promising pathway towards achieving carbon neutrality in consumption. Water electrolysis, utilizing pure water, has proven to be robust technology clean production. Recently, seawater electrolysis emerged as an attractive alternative due the limitations deep-sea regions imposed by transmission capacity long-distance undersea cables. However, faces several challenges, including slow kinetics oxygen evolution reaction (OER), competing chlorine (CER) processes, electrode degradation caused chloride ions, and formation precipitates on cathode. catalyst materials are corroded Cl− under long-term operations. Numerous efforts have been made address these issues arising from impurities seawater. This review focuses recent progress developing high-performance electrodes electrolyser designs efficient electrolysis. Its aim is provide systematic insightful introduction discussion electrolysers with hope promoting offshore sources through

Abstract Seawater direct electrolysis (SDE) using renewable energy provides a sustainable pathway to harness abundant oceanic hydrogen resources. However, the side-reaction of chlorine electro-oxidation reaction (ClOR) severely decreased efficiency seawater and gradually corrodes anode. In this study, redox-mediated strategy is introduced suppress ClOR, decoupled (DSDE) system incorporating separate O 2 evolution reactor established. Ferricyanide/ferrocyanide ([Fe(CN) 6 ] 3−/4− ) serves as an electron-mediator between cell reactor, thereby enabling more dynamically favorable half-reaction supplant traditional oxygen (OER). This alteration involves straightforward, single-electron-transfer anodic without gas precipitation effectively eliminates generation chlorine-containing byproducts. By operating at low voltages (~1.37 V 10 mA cm −2 ~1.57 100 maintaining stability even in Cl − -saturated electrolyte, has potential undergoing with zero emissions. Further improvements high-performance redox-mediators catalysts can provide enhanced cost-effectiveness sustainability DSDE system.

Abstract The design of electrocatalysts for oxygen evolution reaction (OER) remains a limitation industrial hydrogen production by electrolysis water. Excellent and stable OER catalysts can be developed activating lattice changing the path. Herein, S FeOOH on Co(OH) 2 nanoneedle arrays are introduced to construct heterostructure (S‐FeOOH/Co(OH) /NF) as proof concept. Theoretical calculations experimental suggest that Co‐O‐Fe motif formed at heterogeneous interface with introduction FeOOH, inducing electron transfer from Co Fe, enhancing Co─O covalency reducing intramolecular charge energy, thereby stimulating direct coupling. Doping in further accelerates transfer, improves activity, prevents dissolution FeOOH. Consequently, overpotential S‐FeOOH/Co(OH) /NF is only 199 mV 10 mA cm −2 , coupled Pt/C electrode up 1 A under 1.79 V remain over 120 h an anion exchange membrane water electrolyzer (AEMWE). This work proposes strategy efficient promotes commercialization AEMWE.
