中文摘要：

六水氯化镁作为镁源，制备了粒径范围11～26nm的氧化镁，以纳米氧化镁为模板，将聚丙烯酰胺高温炭化，酸溶去模板，制备出高含氮量的多孔炭材料，并对材料进行XRD、SEM、孔径表征和电化学性能测试。结果显示，炭材料以层状为主，平均孔径为4．72nm，比表面积达1873m。／g；在1mol／LH2SO4电解液中，放电电流密度为1A／g时，电板材料的质量比电容达176F／g。

英文摘要：

Porous carbons containing nitrogen were prepared from polyacrylamide using the MgO template meth- od which was produced by magnesium chloride hexahydrate. Particle size range of nanometer MgO was 11- 26nm. After carbons were heat-treated at different temperature in inert atmosphere, MgO formed in the car- bonization products was dissolved out using a diluted acid. Carbon material were characterized by XRD, SEM, pore parameters test and electrochemical measurement. The results showed that porous carbons were layer structure, average pore size was 4.72nm. BET surface area of the carbons obtained could be reached to 1873m2/ g . The specific capacitance 176F/g was obtained at a current density 1A/g in H2SO4.
