Proton exchange membrane water electrolyzer (PEMWE) represents a promising technology for the sustainable production of hydrogen, which is capable efficiently coupling to intermittent electricity from renewable energy sources (e.g., solar and wind). The with compact stack structure has many notable advantages, including large current density, high hydrogen purity, great conversion efficiency. However, use expensive electrocatalysts construction materials leads costs limited application. In...
A comprehensive summary on the developments and status of anode catalysts towards proton exchange membrane water electrolysis technology.
Intermetallics are a large family of structurally ordered alloys that combines metal element with other metal/metalloid elements clearly defined stoichiometric ratio. possess abundant crystal structures and atomic packing motifs, giving rise to great variety electronic configurations surface adsorption properties.

Abstract Long‐term operation of proton exchange membrane water electrolysis (PEMWE) poses significant challenges due to the high potential and strong acidic environment associated with oxygen evolution reaction (OER), leading severe catalyst degradation. Here, ultrafine iridium–ruthenium nanowires (IrRu NWs) are developed through a facile process, which exhibits excellent activity stability for OER. The IrRu NWs achieve an overpotential 243 mV at 10 mA cm −2 , is significantly lower than...
Avoiding lattice oxygen involvement (oxygen redox) while promoting the coupling of adjacent adsorbed (metal during acidic evolution reaction (OER) is essential for gaining high activity and robust stability in RuO2‐based catalysts but remains elusive. Here, we present a precise strategy to selectively activate metal redox process suppressing undesired pathway by fine‐tuning Ru‐O coordination number amorphous RuOx. The optimized catalyst exhibits outstanding OER performance, achieving low...

Developing efficient Ru‐based catalysts is crucial in reducing reliance on costly Ir for the acidic oxygen evolution reaction (OER). However, these face a fundamental stability challenge due to highly reactive nature of lattice oxygen. In this work, we propose an effective strategy stabilize two‐dimensional amorphous RuOx through p‐p orbital hybridization by incorporating dopants such as Al, Ga, and In. Notably, Ga doping exhibits remarkable OER performance, leads 137 mV reduction...
RuO2 has been considered as a promising, low-cost, and highly efficient catalyst in the acidic oxygen evolution reaction (OER). However, it suffers from poor stability due to inevitable involvement of lattice mechanism (LOM). Here, we construct unique metallene-based core-skin structure unveil that OER pathway atomic skin can be regulated LOM an adsorbate by altering core species metallene oxides metallenes. This switch is achieved without sacrificing number active sites, enabling Pd@RuO2...
