The oxygen reduction reaction (ORR) is one of the most critical reactions in energy conversion systems, and it facilitates the efficient conversion of chemical energy into electrical energy, which is necessary for modern technology. Developing efficient and cost-effective catalysts for ORRs is crucial for advancing and effectively applying renewable energy technologies such as fuel cells, metal-air batteries, and electrochemical sensors. In recent years, iron porphyrin-based composites have emerged as ideal catalysts for facilitating effective ORRs due to their unique structural characteristics, abundance, advances in synthesis, and excellent catalytic properties, which mimic natural enzymatic systems. However, many articles have focused on reviewing porphyrin-based frameworks or metalloporphyrins in general, necessitating research specifically addressing iron porphyrin. This review discusses iron porphyrin as an effective catalyst in ORRs. It provides a comprehensive knowledge of the application of iron porphyrin-based composites for electrocatalytic ORRs, focusing on their properties, synthesis, structural integration with conductive supports, catalytic mechanism, and efficacy. This review also discusses the challenges of applying iron porphyrin-based composites and provides recommendations to address these challenges.
氧还原反应（ORR）是能量转换系统中最关键的反应之一，它有助于将化学能高效转化为电能，这对现代技术至关重要。开发用于ORR的高效且经济高效的催化剂对于推进和有效应用可再生能源技术（如燃料电池、金属空气电池和电化学传感器）至关重要。近年来，基于铁卟啉的复合材料因其独特的结构特征、丰富性、合成进展和优异的催化性能（模仿天然酶系统）而成为促进有效ORR的理想催化剂。然而，许多文章通常侧重于综述基于卟啉的框架或金属卟啉，因此有必要专门针对铁卟啉进行研究。本综述讨论了铁卟啉作为ORR中有效催化剂的情况。它全面介绍了基于铁卟啉的复合材料在电催化ORR中的应用，重点关注其性质、合成、与导电载体的结构整合、催化机制和功效。本综述还讨论了应用基于铁卟啉的复合材料所面临的挑战，并提出了解决这些挑战的建议。
