Advanced Sustainable Systems, Год журнала: 2025, Номер unknown

Опубликована: Апрель 10, 2025

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.

Abstract Hydrogen evolution reaction (HER) under alkaline conditions is determined by the water dissociation process. Strengthening adsorption ability of electrocatalyst crucial to promoting in HER, whereas too‐intense will poison active sites. Herein, NiFeP modulated nonmetal F doping for an efficient and durable HER. incorporation (NiFePF) tailors electronic structure Ni, Fe, P, optimizing * OH/ H on The balanced facilitates hydrogen NiFePF, exhibiting smaller overpotential 233 mV at 100 mA cm −2 . Furthermore, NiFePF achieves 1 A only 231 30 wt% KOH. desorption OH alleviates poisoning center, limiting surface hydroxylation a few nanometers. This enables remain stable 360 h, demonstrating its commercial potential.
