Water electrolysis driven by "green electricity" is an ideal technology to realize energy conversion and store renewable into hydrogen. With the development of proton exchange membrane (PEM), water in acidic media suitable for many situations with outstanding advantage high gas purity has attracted significant attention. Compared hydrogen evolution reaction (HER) electrolysis, oxygen (OER) a kinetic sluggish process that needs higher overpotential. Especially media, OER poses requirements electrocatalysts, such as efficiency, stability low costs. This review focuses on electrocatalysis, mechanisms, critical parameters used evaluate performance. modification strategies applied design construction new-type electrocatalysts are also summarized. The characteristics traditional noble metal-based metal-free developed recent decades compared discussed. Finally, current challenges most promising presented, together perspective future electrolysis.

The oxygen evolution reaction (OER) performance of ruthenium-based oxides strongly correlates with the electronic structures Ru. However, widely adopted monometal doping method unidirectionally regulates only structures, often failing to balance activity and stability.

Abstract Hydrogen, a clean resource with high energy density, is one of the most promising alternatives to fossil. Proton exchange membrane water electrolyzers are beneficial for hydrogen production because their current facile operation, and gas purity. However, large‐scale application electrochemical splitting acidic electrolytes severely limited by sluggish kinetics anodic reaction inadequate development corrosion‐ highly oxidation‐resistant anode catalysts. Therefore, catalysts excellent performance long‐term durability must be developed oxygen evolution reactions (OER) in media. This review comprehensively outlines three commonly employed strategies, namely, defect, phase, structure engineering, address challenges within OER, while also identifying existing limitations. Accordingly, correlation between material design strategies catalytic discussed terms contribution activity stability. In addition, various nanostructures that can effectively enhance catalyst at mesoscale summarized from perspective engineering technology, thus providing suitable satisfy industrial requirements. Finally, future outlook area OER presented.

Abstract Proton exchange membrane (PEM) water electrolysis presents considerable advantages in green hydrogen production. Nevertheless, oxygen evolution reaction (OER) catalysts PEM currently encounter several pressing challenges, including high noble metal loading, low mass activity, and inadequate durability, which impede their practical application commercialization. Here we report a self-constructed layered catalyst for acidic OER by directly using an Ir–Ta-based metallic glass as the matrix, featuring nanoporous IrO 2 surface formed situ on amorphous IrTaO x nanostructure during OER. This distinctive architecture significantly enhances accessibility utilization of Ir, achieving activity 1.06 A mg Ir −1 at 300 mV overpotential, 13.6 31.2 times greater than commercial Ir/C , respectively. The also exhibits superb stability under industrial-relevant current densities acid, indicating its potential uses. Our analyses reveal that coordinated nature surface-active species is effectively modulated through electronic interaction between Ta, preventing them from rapidly evolving into valence states suppressing lattice participation. Furthermore, underlying dynamically replenishes depletion sites inward crystallization selective dissolution, thereby ensuring catalyst’s long-term durability.
