Improving the utilization of iridium in proton exchange membrane (PEM) water electrolyzer is critical reducing their cost for future development. Titanium dioxide (TiO2) has notable electrochemical stability at high operating potential and been developed as a promising support iridium-based OER nano-catalysts. However, limited by insufficient conductivity, content on TiO2 catalysts normally above 50 wt.%. Herein, provided conductivity-enhanced low-iridium-loading PEMWE, successfully to 28 wt.% regulation electron transport pathway. A new ionomer distribution strategy then applied Ir@Pt@TiO2 catalyst layer release sites regulate local mass pathways anode. This work reveals that catalyst-ionomer interface played an important role activity anode PEMWE. Building thin uniform supports with exposure can result continuous pathways, promoting bubble escape, exposing more effective active during reaction situations. provides novel perspective research PEMWEs.

Abstract The development of innovative electrocatalysts for seawater splitting shows great potential large‐scale green energy. Specifically, interface engineering plays a vital role in improving surface properties and charge transfer. However, electrolysis encounters considerable challenges like chloride‐induced corrosion, impurities, microorganisms that hinder efficiency. Herein, we design highly durable electrocatalyst based on selenium‐enriched NiMn‐S x supported low‐density polyethylene‐derived spherical carbon‐Ni foam (Se‐NiMnS @SC/NF) using combination pyrolysis hydrothermal processes. resulting Se‐NiMnS @SC/NF bifunctional catalyst with hollow cycas cone structure exhibited exceptional electrochemical performance corrosion resistance alkaline an ultralow overpotential 146 262 mV the hydrogen evolution reaction (HER) oxygen (OER) to achieve large current density 500 mA cm⁻ 2 . In simulated setup, maintained cell voltage 2.07 V at , demonstrating outstanding durability over 100 h ≈100% Faradaic Se S doping heterostructured refines electronic boosts kinetics, while increases exposure active sites. Additionally, carbon layer provided strong making excellent electrolysis.

Abstract Hydrogen production by electrochemical water splitting is considered to be a key strategic energy technology, and proton exchange membrane electrolyzers (PEMWEs) anion (AEMWEs) are ideal technologies for green hydrogen in recent years. However, PEMWEs AEMWEs lack low‐cost high‐performance acidic oxygen evolution reaction (OER) alkaline (HER) electrocatalysts respectively, limiting their large‐scale development. Recently, ruthenium (Ru)‐based have received lot of attention because activity better than that commercial catalysts price more affordable, showing great potential OER HER. there still obstacles Ru‐based practical applications industrial electrolyzers, regulatory strategies need developed further optimize its performance. Herein, comprehensive review presented concerning it. First, fundamental principles focus the basic content application discussed. Then, summarized, providing detailed analysis elucidate mechanisms, properties, electrolyzers. Finally, outlooks prospects challenges future proposed.
