Abstract: Using industrial filter paper as carbon-based material, Pluronic F127 as soft template,1,3,5-trimethylbenzene aspore-expanding agent, paper-based composite materials were prepared through hydrothermal synthesis reaction from 3-aminophenol (nitrogen source) and hexamethylenetetramine. Nitrogen-doped mesoporous carbon materials(NMC-700) was obtained by carbonization, and actived NMC(ANMC-700) was prepared by KOH activation. At the same time,the carbon-700(C-700) samples were obtained by direct carbonization of industrial filter paper and used as the control sample. Three carbonized materials were characterized by SEM, TEM, XRD and XPS. The results showed that carbon microspheres with particle size of 0.6-7 μm were formed on the surface of ANMC-700. And the pore structure was consisted of randomly distributed, worm-like pores with specific surface area of 1 559 m2/g and pore volume of 0.80 cm3/g. The nitrogen atom was successfully doped into the carbon skeleton with the nitrogen content of 3.60% and the oxygen content of 13.65%. Electrochemical performance test results showed that the capacitance of the prepared carbon materials could reach 284 F/g at the current density of 1 A/g in 6 mol/L KOH electrolyte, and could retain 173 F/g at the current density of 20 A/g, exhibiting outstanding cycling stability(98.6% capacitance retention after 10 000 charge/discharge cycles).
