摘　　要：发展氢燃料电池是解决现今能源问题的一项重要策略.燃料电池阴极氧还原反应的效率是影响整体能量转换效率的关键.受自然界细胞色素c氧化酶的启发,金属大环卟啉化合物已经作为氧还原反应催化剂被广泛研究,并表现出良好的催化性能.本文综述了金属卟啉类化合物在电催化氧还原反应的应用,主要包括金属卟啉的meso-位取代基、β-位取代基、轴向配体、第二配位层、双核金属、不同金属中心以及碳基材料等因素对电催化氧还原反应活性和选择性的影响.此外,本文还展望了金属卟啉类催化剂的后续研究方向.The development of H_(2)-O_(2)fuel cell technology is an important strategy to solve the current energy problem.The catalytic efficiency of oxygen reduction reaction(ORR)on the cathode of fuel cell is a key factor that affects the overall energy conversion efficiency.Inspired by cytochrome c oxidases(CcOs)in nature,the researchers have studied many metal macrocyclic porphyrin complexes as ORR catalysts which show excellent electrocatalytic activity for ORR.This review addresses the current status of metal porphyrins in ORR,including the effects of meso-and β-substituents,axial ligands,second coordination spheres,binuclear metal,different metal centers,and carbon-based materials on the catalytic activity and selectivity of ORR.Furthermore,the future research direction of metal porphyrin catalysts is also predicted.
