非贵金属-氮掺杂碳材料应用于质子交换膜燃料电池中催化氧气还原反应(ORR)，具有低成本、高活性和高循环使用寿命等优点，但该材料中活性位点的结构和含量一直是制备的难点。.本项目采用化学合成法将金属次卟啉固载在氨基修饰的模板表面，再以含氮聚合物包裹，经热解和除模板后构筑多层次中空碳球，其中该碳壳的内外表层含N-Cx活性位点，碳壳的中间层主要是由金属次卟啉提供的M-Ny-Cx活性位点（M为金属离子；x, y=0~4）。该设计思路不仅利用了中空碳球高比表面积和丰富的介孔通道等的特点，而且利用了碳壳层次结构对M-Ny-Cx活性位点提供抗氧化保护作用，增强其稳定性和循环使用寿命，同时两相活性位点之间也能产生协同催化ORR。.此外，通过比较研究金属次卟啉、金属四苯基卟啉及金属酞菁在可控热解条件下获得活性位点的类型、含量以及在ORR中的作用机制，有利于深化环状四吡咯大环化合物在燃料电池应用中的理论知识。

N-doped carbon materials, with its low-cost, superior activity and high durability have a broad commercial application prospect in the fields of proton exchange membrane fuel cell (PEMFC) for oxygen reduction reaction (ORR). However, the quantitative preparation of the structure and content of active sites are more challenging. .This project aims to construct the multi-layer hollow carbon spheres containing both N-Cx and M-Ny-Cx active sites (M for metal ion ; x, y=0~4) by chemical grafting synthetic method, which contains four steps such as the immobility of metallo-deuteroporphyrin on the modified template, covering with polynitrogen compounds, the pyrolysis, and removing template. This constructionn strategy for multi-layer hollow carbon spheres has several important benefits: (i) the high activity of M-Ny-Cx was derived from metallo-deuteroporphyrin and the N-Cx active site was distributed in the inside and outside layer of carbon shell. The interaction of two active sites can provide the excellent catalytic activity. (ii) the M-Ny-Cx active site was embedded into carbon layer, which was resulted in improving the catalytic activity and durability. .Moreover, based on the result of the difference in the type, the feasibility, the active site, and the ORR mechanism of three compounds (metallo-deuteroporphyrin, metallo-tetraphenylporphyrin and metallo-phthalocyanine), it would be better to understand the theoretical knowledge of fuel cell applications in hetero-macrocyclic compounds, and will make great contribution to promote the development of fuel cell.
