| 中文摘要: |
| 电解水制氢是实现绿色氢经济的关键技术,其阳极的氧析出反应(OER)动力学迟缓,是全流程能耗的主要来源。以镍铁基催化剂为代表的非贵金属材料,因其高活性与低成本而成为研究焦点。本文聚焦于近年来阴离子交换膜水电解槽背景下的OER催化剂,从反应机理的深化理解、催化剂设计策略(特别是界面与缺陷工程)以及稳定性的核心挑战与应对方案三个层面,系统评述了该领域的最新研究动态。特别是在揭示“吸附质演化机制”与“晶格氧氧化机制”的双路径共存与调控,以及面向高电流密度、长寿命运行的催化剂离子损失与结构性退化抑制策略方面取得了重要进展。最后,本文从机理探索、材料工程与器件评估三个维度展望了电解水催化剂未来迈向大规模工业应用的发展方向。 |
| 英文摘要: |
| Water electrolysis is a key technology for green hydrogen economy, and the sluggish kinetics of the anodic oxygen evolution reaction (OER) is the major source of energy consumption. Non-precious metal catalysts, represented by nickel-iron (NiFe)-based materials, have become the research focus due to their high activity and low cost. This review focuses on the recent progress of OER catalysts in the context of anion exchange membrane water electrolyzers. We systematically summarize the latest research trends from three aspects: the in-depth understanding of reaction mechanisms, catalyst design strategies (especially interface and defect engineering), and the core challenges and countermeasures for stability. Significant advances have been made in revealing the coexistence and regulation of the dual pathways of "adsorbate evolution mechanism" and "lattice oxygen oxidation mechanism", as well as strategies for suppressing ion leaching and structural degradation for high-current-density and long-term operation. Finally, future development directions for water electrolysis catalysts towards large-scale industrial application are prospected from three dimensions: mechanism exploration, material engineering, and device evaluation. |
