摘要
氢气被认为是一种清洁的能源载体。作为应对全球能源挑战的潜在解决方案,各类可再生能源制氢工艺已受到广泛关注。质子交换膜(PEM)电解水技术具有启动和功率调节迅速的优点,是目前唯一可以耦合可再生能源发电制备高纯度氢气的技术。催化剂是PEM电解水反应的关键材料,尤其是阳极侧的析氧催化剂。本文首先回顾了4类主流的电解水制氢技术,随后概述了铱基和钌基电催化剂在酸性析氧反应中的最新研究进展,特别强调了对活性/稳定性增强策略的讨论。最后,总结了该领域存在的问题和所面临的挑战,并对未来的研究方向做出了展望。
Hydrogen is considered as a clean energy carrier in the global energy transition and development due to its high energy density(142 kJ·g^(–1)),cleanliness,and sustainability.At present,hydrogen is mainly produced through steam reforming of fossil fuels under harsh conditions,which are restrained by the complex operation and emission of carbon dioxide.Hydrogen production through water electrolysis is an effective and clean method for generating high-purity hydrogen using renewable energy sources without pollution.The electricity utilized in this process is obtained from renewable sources such as solar,hydropower,wind,and nuclear energy,enabling carbon-free and green hydrogen production.With the advancements in renewable energy generation technologies and electrolysis cell techniques over the past a few decades,the production of green hydrogen through water electrolysis is flourishing.Based on the type of electrolyte and operating conditions,water electrolysis technologies are primarily classified into four categories,i.e.,alkaline water electrolysis(AWE),proton exchange membrane(PEM)water electrolysis,anion exchange membrane(AEM)water electrolysis,and solid oxide electrolysis cell(SOEC)water electrolysis.PEM water electrolysis technology,distinguished by its prompt start-up and power modulation capabilities,is currently a sole technology capable of producing high-purity hydrogen coupled with renewable energy generation.This review firstly introduced several major hydrogen production technologies,emphasizing the advantages of PEM water electrolysis technology.Subsequently,we represented the latest developments in iridium(Ir)and ruthenium-based(Ru)oxygen evolution reaction(OER)electrocatalysts in acidic electrolyte,and summarized the strategies for developing acidic OER electrocatalysts with a high performance.Finally,this review highlighted the challenges associated with acidic OER electrocatalysts and outlined prospective avenues for future research.The electrolysis efficiency of PEM water electrolysis primaril
