Abstract

Proton exchange membrane water electrolysis (PEMWE), powered by renewable electricity, offers a promising route for clean hydrogen production. However, the oxygen evolution reaction (OER) at the anode significantly hinders the overall efficiency of PEMWEs due to its sluggish kinetics. This necessitates the development of robust and active OER catalysts in acidic media. Iridium (Ir)-based materials have emerged as the most promising candidates for acidic PEMWE OER. This review highlights the growing interest in metal-organic frameworks (MOFs) as potential OER catalysts, emphasizing their tunable porous structures. Furthermore, recent advancements in ruthenium (Ru)-based electrocatalysts for the hydrogen evolution reaction (HER) are discussed, showcasing Ru as a cost-effective and durable alternative to platinum (Pt). Strategies to enhance the performance of Ru-based HER electrocatalysts are explored, underscoring their crucial role in advancing hydrogen energy technologies and facilitating the transition to a sustainable hydrogen economy. Finally, the review addresses the long-term durability challenges faced by various electrocatalysts in acidic conditions, providing insights into the status, challenges, and prospects for the development of stable and efficient electrocatalysts.

酸性OER和HER电催化剂的进展：用于可持续制氢的铱、mof和钌系统

质子交换膜水电解（PEMWE）是一种由可再生电力提供动力的清洁制氢方法。然而，阳极的析氧反应（OER）由于其缓慢的动力学而严重阻碍了PEMWEs的整体效率。这就需要在酸性介质中开发坚固和活性的OER催化剂。铱（Ir）基材料已成为酸性PEMWE OER最有希望的候选材料。这篇综述强调了金属有机框架（MOFs）作为潜在的OER催化剂的日益增长的兴趣，强调了它们可调的多孔结构。此外，还讨论了用于析氢反应（HER）的钌基电催化剂的最新进展，表明钌是铂（Pt）的一种具有成本效益和耐用性的替代品。探讨了提高ru基HER电催化剂性能的策略，强调了它们在推进氢能技术和促进向可持续氢经济过渡方面的关键作用。最后，综述了各种电催化剂在酸性条件下面临的长期耐久性挑战，并对稳定高效电催化剂的发展现状、挑战和前景进行了展望。
