Strategies for Designing Anti‐Chlorine Corrosion Catalysts in Seawater Splitting

Advanced Energy Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 18, 2025

Abstract The seawater splitting for green hydrogen production is emerging as a key research focus sustainable energy. Nevertheless, the inherent complexity of seawater, with its diverse ion composition – especially chloride ions, calcium and magnesium ions poses significant challenges in catalyst design. Designing highly active electrocatalysts that can resist corrosion during still challenge. This article presents an overview fundamental mechanisms explores issues encountered at both cathode anode electrode. then shifts to chlorine anode, examining recent advances preventing strategies. Notably, these design strategies, such anionic passivation layers, corrosion‐resistant metal doping, physical barrier situ phase transition‐driven desalination, decoupled splitting, are comprehensively investigated, all which aim enhance catalytic stability splitting. review concludes outlook on practical applications producing through

Published: March 5, 2025

Abstract Electrocatalytic water splitting has emerged as a key method for large‐scale production of green hydrogen. Constructing efficient, durable, and low‐cost electrocatalysts the hydrogen evolution reaction at high current densities is prerequisite practical industrial applications splitting. Recently, non‐noble metal‐based self‐supporting electrodes have been explored density due to their cost‐effective, conductivity metal substrate, robust interfacial binding between catalyst strong mechanical stability. In this review, recently reported (Ni, Fe, Cu, Co, Ti, Mo, alloy) electrode applied are comprehensively summarized, classified, discussed. Five fundamental design principles such intrinsic activity, abundant active sites, fast electron transfer, mass transport, stability proposed discussed achieve high‐performance under densities. Furthermore, various modification strategies including heteroatom doping, morphology engineering, interface phase strain engineering enhance catalytic activity durability electrode. Finally, challenges prospects designing efficient stable in future This comprehensive overview will provide valuable insight guidance development production.

Stimulating and Stabilizing Ultrafine Pt Clusters on Metalloid Support as Dual‐Site Electrocatalyst in High‐Density Seawater Electrolysis and Anion Exchange Membrane Electrolyzer

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: March 16, 2025

Abstract Constructing synergistic dual sites has been well‐recognized as an updated avenue in constructing binary‐component Pt/support compounds such materials undergo undesirable interfacial barriers and complicated synthesis. Here integration of ultrafine Pt nanocrystals on oxygen‐deficient CoMoO 4 nanosheets is reported that achieved superior alkaline hydrogen evolution reaction (HER) activity (110 mV @ 1000 mA cm −2 ) with a reversed deliver effect between bifunctional active sites. With perceptions from comprehensive experimental theoretical results, the HER process occurs three steps: pronounced water dissociation capability , facile transfer to nanoparticles, optimized desorption catalytic site. Thanks site effect, Pt/CoMoO catalyst boosts large‐density seawater electrolysis anion exchange membrane electrolyzer (AEM). This work not only provides valid intensification strategy aimed at support‐type electrocatalysts but also takes insights into dual‐site mechanisms for high‐performance HER.
