At present; Synthetic or preparation nitrogen-doped carbon material mainly contains following several method: a kind of is in synthetic material with carbon element process; By using nitrogenous precursor to realize nitrogen doping purpose as carbon source, but since in the nitrogenous precursor pyrolytic process a large amount of nitrogen be difficult to obtain high nitrogen doping with the form loss of gas, and the process of removal catalyst can be destroyed carbonaceous material intrinsic structure (Sen usually; R. Satishkumar, B. C.; Govindaraj, A.; Et al., Nitrogen-containing carbon nanotubes, J. Mater. Chem., 1997,7 (12): 2335); Another kind is to carry out the nitrogen doping by synthetic material with carbon element being carried out surface chemical modification, like strong acid or NH
3Can realize the available nitrogen of material with carbon element is mixed Deng chemical treatment method, but this kind processing mode also can cause the original structure of material with carbon element to be destroyed when introducing nitrogenous sense; Like (Arrigo such as electric conductivity reductions; R, Havecker, M. Schlogl; R. Su; D. S, Dynamic surface rearrangement and thermal stability of nitrogen functional groups on carbon nanotubes Chem. Commun., 2008:4891); Adopting nitrogenous organic solvent that material with carbon element is carried out the nitrogen doping is a kind of gentle relatively method, because carbonaceous material and organic solvent have good intermiscibility, helps that material with carbon element is carried out even nitrogen and mixes; And can obviously not destroy the original structure feature of material with carbon element, but its itrogen content of getter with nitrogen doped lower (Li Lixiang, Liu Yongchang; Geng Xin, An Baigang, the preparation of nitrogen-doped carbon nanometer pipe and Electrochemical Properties; Acta PhySico-Chimica Sinica, 2011,27:443).
