氧还原反应是燃料电池、金属-空气电池等众多可持续能源转换技术的核心反应。开发一种低成本、高活性、耐用的ORR电催化剂以克服四电子途径的迟滞动力学是至关重要的。近年来，基于金属有机骨架(MOF)的碳基电催化剂引起了人们的极大关注，并显示出优异的催化活性和优异的固有性能，如大比表面积、大孔容、均匀的孔分布和可调的化学结构。本文综述了MOF衍生的杂原子掺杂碳基电催化剂的研究进展，包括非金属(如N、S、B、P)和金属(如Fe、Co)掺杂的碳材料。此外，研究还表明，ORR性能的提高与良好的多孔结构、大的比表面积和高强度的活性中心有关。最后，展望了有机还原反应用碳基电催化剂的发展前景，重点发展了MOF衍生的非金属掺杂和某些金属掺杂的碳基电催化剂的清晰机理。
The oxygen reduction reaction (ORR) is the core reaction of numerous sustainable energy‐conversion technologies such as fuel cells and metal–air batteries. It is crucial to develop a cost‐effective, highly active, and durable electrocatalysts for ORR to overcome the sluggish kinetics of four electrons pathway. In recent years, the carbon‐based electrocatalysts derived from metal–organic frameworks (MOFs) have attracted tremendous attention and have been shown to exhibit superior catalytic activity and excellent intrinsic properties such as large surface area, large pore volume, uniform pore distribution, and tunable chemical structure. Here in this review, the development of MOF‐derived heteroatom‐doped carbon‐based electrocatalysts, including non‐metal (such as N, S, B, and P) and metal (such as Fe and Co) doped carbon materials, is summarized. It furthermore, it is demonstrated that the enhancement of ORR performance is associated with favorably well‐designed porous structure, large surface area, and high‐tensity active sites. Finally, the future perspectives of carbon‐based electrocatalysts for ORR are provided with an emphasis on the development of a clear mechanism of MOF‐derived non‐metal‐doped electrocatalysts and certain metal‐doped electrocatalysts.
