Energy storage and conversion adopting electrochemical method is an important development trend of modern green energy. And the research on advanced electrode materials is the core of field of electrochemical energy. The project aims at developing a new method of preparing N-doped carbon nanomaterials controllably using biomass. Based on the full knowledge to the characteristics of structure, composition and pyrolysis of the basic biomass components such as cellulose etc, the sole biomass components and multi-biomass components were doped with nitrogen under high temperature. The reaction kinetics of various systems and the correlationships between the morphology, structure and composition of carbon sources and those of products were researched systematically. Thus the common laws of preparing N-doped carbon namomaterials using carbon source constructed by sole biomass components were obtained. In addition, some typical natural biomsses and multi-biomass simulative systems were doped with nitrogen under high temperature and the reaction kinetics, morphology, structure, composition and electrochemical property of the N-doped nanomaterials were compared. And the specific laws of preparing N-doped carbon namomaterials using natural biomasses were also discussed. Therefore, N-doped carbon nanomaterials with expected morphology, structure, composition and electrochemical property can be prepared controllably through the meticulous design of the carbon source constructed by sole biomass components, rational choice and control of nitrogen source and heat treatment conditions.
