摘要

In this paper

nitrogen-doped hierarchical porous carbon (N-HPC) was prepared from polyaniline (PANI)/silica self-aggregates. H-bonding between N-H groups in aniline/PANI and -OH groups in nano silica temp

late led to a self-assembly type

which enabled the formation of uniform N-HPC nanoparticles. Silica self-aggregates provided macroporous channels resulted in a decreased diffusion distance. After removing the hard template

the N-HPC had a high surface area (899 m

·g

-1

). Owing to two co-existed synergetic energy-storage mechanisms and the hierarchical porous structure

the obtained N-HPC exhibited a high specific capacitance of 218.75 F·g

-1

at 0.5 A·g

-1

compared with the nonporous nitrogen-doped carbon (N-C) derived from pure PANI. Moreover

the N-HPC electrode demonstrated excellent cycle life

retaining 99% of its initial specific capacitance after 1000 cycles.
