据认为，Fe-N在碳网络中的存在有助于增强碳的氧还原反应（ORR）活性。本研究以酞菁铁为氮源、铁源和碳源的单一前驱体，制备了氮掺杂的片状有序介孔碳。我们表明，铁的物理存在是没有必要的，以提高氮掺杂的碳的ORR活性，虽然铁是需要创造更多的活性位点，并增加在碳框架的电导率。
It has been considered that the presence of Fe-N in the carbon network helps to enhance oxygen reduction reaction (ORR) activity of the carbon. In this study, N-doped platelet ordered mesoporous carbon is prepared using Fe-phthalocyanine as a single precursor for nitrogen, iron and carbon sources. We show that the physical presence of Fe is not necessary to enhance the ORR activity of N-doped carbon, although Fe is required to create more active sites and to increase the electrical conductivity in the carbon framework.
