合成了一系列石墨烯-金属四苯基卟啉（GR-MTPP)的复合材料，并将该复合材料作为电催化剂应用于氧气还原反应中。通过金属离子与四苯基卟啉发生配位反应得到金属四苯基卟啉（FeTPP、CoTPP、NiTPP、CuTPP、ZnTPP、MnTPP)，进一步通过π-π堆积作用合成了一系列新型的石墨烯-金属卟啉复合材料，并将其修饰到玻碳电极上，研究其催化氧气还原的反应。结果表明，该复合材料在 DMF 与水的混合溶剂中分散性能良好；石墨烯与金属卟啉的协同作用使其催化氧气还原性能更优；该类复合材料尤其是GR-FeTPP 与 GR-CoTPP 在中性溶液中（pH=7.0)显示出良好的对氧气还原的电催化性能。 GR-FeTPP 催化氧气还原的电位在-0.24 V 处，响应电流为85μA；GR-CoTPP 催化氧气还原的电位在-0.19 V，响应电流为44μA。表明石墨烯-金属卟啉复合材料是氧气传感器良好的电催化剂。

A series of graphene-metal-tetraphenylporphyrin(GR-MTPP) nanocomposite materials were prepared and applied in the oxygen reduction reaction as efficient electrocatalysts. MTPPs (FeTPP,CoTPP,NiTPP,CuTPP,ZnTPP and MnTPP) were synthesized via a coordination reaction between metal ions and TPP. Graphene -metal -tetraphenylporphyrin nanocomposition materials were successfully prepared by the π -π stacking interaction and applied in the electrocatalytic oxygen reduction reaction. The results showed that GR-MTPPs exhibited enhanced electrocatalytic activity toward oxygen reduction due to the synergistic effect between the graphene and MTTP. The large electro-active surface area and fast charge transfered of graphene facilitated the electrocatalytic oxygen reduction of MTPP. The GR-FeTPP showed the peak potential at -0.24 V with the current response of 85 μA for the eletrocatalytic reduction of oxygen. The GR-CoTPP showed the peak potential at -0.19 V with the current response of 44 μA for the eletrocatalytic reduction of oxygen. It is indicated that GR-MTPP nanocomposite materials are prominent electrocatalysts for oxygen sensors.
