Abstract Proton exchange membrane water electrolyser (PEMWE) possesses great significance for the production of high purity hydrogen. To expedite anodic oxygen evolution reaction (OER) that involved multiple electron–proton‐coupled process, efficient and stable electrocatalysts are highly desired. Currently, noble‐metal Ir‐based materials benchmark anode due to its corrosion‐resistant property favourable combination activity/stability. However, large‐scale deployment PEMWE is usually constrained use scarcest element iridium. In this review, we disclose current research progress towards non‐iridium‐based OER in acidic media, then summarize some typical oxides good catalytic performance. Besides, also present unresolved problems challenges an attempt enhance activity/stability these catalysts.

Abstract Alkaline electrolysis plays a crucial role in sustainable energy solutions by utilizing electrolytic cells to produce hydrogen gas, providing clean and efficient method for storage conversion. Efficient, stable, low‐cost electrocatalysts the oxygen evolution reaction (OER) are essential facilitate alkaline water on commercial scale. Nickel‐iron‐based (NiFe‐based) transition metal considered most promising non‐precious catalysts OER due their low cost, abundance, tunable catalytic properties. Nevertheless, majority of existing NiFe‐based suffer from limited activity poor stability, posing significant challenge meeting industrial applications. This also highlights common situation where emphasis material receives attention, while equally critical stability aspect is often underemphasized. Initiating with comprehensive exploration materials, this article first summarizes debate surrounding determination active sites electrocatalysts. Subsequently, degradation mechanisms recently reported outlined, encompassing assessments both chemical mechanical endurance, along approaches enhancing stability. Finally, suggestions put forth regarding considerations design electrocatalysts, focus heightened

Abstract Design and construction of stable single‐atom modified catalysts with suppressed deep reconstruction for long‐term durability highly active targeted catalysis in emains a great challenge. Herein, nitrogen/oxygen co‐doped carbon (NOC) encapsulated Mo atomically dispersed at Co 3+ sites 3 O 4 , are constructed through directed corrosion strategy. Meanwhile, the NOC confinement maintains stability single atoms promotes adsorbate evolution into lattice oxygen‐mediated mechanism. The reconstructed CoOOH is confined by layer, thus inhibiting its reconstruction, electrostatically repelling chloride ions to achieve electrolysis seawater. In real seawater flow cell, electrode requires 1.94 V reach 1.0 A cm −2 energy consumption 4.64 kWh Nm −3 ‐H 2 lower than that industrial alkaline electrolysis. continuous 300 h shows almost no decay, Faraday efficiency close 100%, indicating long‐lasting stability.

Compositional complex alloys, including high and medium-entropy alloys (HEAs/MEAs) have displayed significant potential as efficient electrocatalysts for the oxygen evolution reaction (OER), but their structure-activity relationship remains unclear. In particular, basic question of which crystal facets are more active, especially considering surface reconstructions, has yet to be answered. This study demonstrates that lowest index {100} FeCoNiCr MEAs exhibit highest activity. The underlying mechanism associated with facet's low in-plane density, making it easier reconstruction form amorphous structures containing true active species is uncovered. These results validated by experiments on single crystals polycrystal MEAs, well DFT calculations. discoveries contribute a fundamental comprehension in electrocatalysis offer physics-based strategies developing electrocatalysts.
