Conclusions
A templateꢀfree and oneꢀstep method is developed to prepare
hierarchical porous carbon materials, that is direct
carbonization of phenolic resin carboxylic salt xerogels. A
microporous carbon material with narrow pore size distribution
is also facilely prepared by hydrothermalꢀtreated resin

hydrogels. The HPCꢀ
x samples possess typical hierarchical
porosity simultaneous possessing interconnected mesopores
and developed micropores with very short length. Due to its
unique pore texture, the HPCꢀ9d carbon shows superior
capacitive performance with high specific capacitance,
excellent rate capability, and good longꢀterm cycle stability in
KOH and TEABF4/AN electrolyte. In a word, the method
employed in this work is facile and easy to handle, and the
prepared carbon materials are promising for supercapacitors
combined high energy density and high power output.
