Oxygen-reduction reaction (ORR) is the most critical factor in energy conversion technologies such as fuel cells. Barriers such as the high cost of Pt and its scarce reservoirs worldwide limit the use of the most advanced Pt-based catalysts for the ORR reaction. Metal–organic frameworks (MOFs) have attracted considerable attention for the production of carbon-based nonprecious metal electrocatalysts (NPMC) due to their cost-effective properties and adjustment of MOF as precursors. The new insight of this review article is focused on clarification of synthesis-structure-activity correlations of the presented ORR electrocatalysts for fuel cell applications. Classification of different MOF precursors and their final desirable electrocatalysts after the pyrolysis process are discussed. ORR performance (activity and stability) and their fuel cell performances are investigated for different MOF-derived materials like monometallic, bimetallic composites, and even single-atom electrocatalysts. Eventually, readers find a deeper understanding and inspiration of the emerging field of nonprecious MOF-derived catalysts.

来自MOFs的碳基非贵金属电催化剂用于氧还原反应

氧还原反应 (ORR) 是燃料电池等能量转换技术中最关键的因素。Pt 的高成本及其在全球范围内的稀缺储层等障碍限制了最先进的 Pt 基催化剂在 ORR 反应中的使用。金属-有机骨架（MOF）由于其具有成本效益的特性和作为前体的 MOF 的调整，在碳基非贵金属电催化剂（NPMC）的生产中引起了相当大的关注。这篇评论文章的新见解侧重于阐明所提出的用于燃料电池应用的 ORR 电催化剂的合成-结构-活性相关性。讨论了热解过程后不同 MOF 前体的分类及其最终理想的电催化剂。研究了不同 MOF 衍生材料（如单金属、双金属复合材料甚至单原子电催化剂）的 ORR 性能（活性和稳定性）及其燃料电池性能。最终，读者对非贵重的 MOF 衍生催化剂这一新兴领域有了更深入的了解和启发。
