For the first time,In-situ N-doped mesoporous carbon materials were synthesized by hydrothermal process with chitosan-oligosaccharide as C—N source and F127 as template.The samples were characterized by N2 adsorption/desorption isotherm,XRD etc.The effects of F127 addition,stirring temperature and stirring time on pore structure of the materials were discussed.The results showed that the optimum preparation conditions were as follows:the additive amount of F127 was 0.5g,the reaction temperature was 50℃,and the stirring time was 4h.Nitrogen was successfully doped In-situ into mesoporous carbon materials,and its content was 6.88%.The specific surface area and mesoporous volume were 403m2/g and 0.83cm3/g,respectively.
