Abstract

N-doped porous carbon nanosheets were prepared from glucose with g-C 3 N 4 derived from dicyandiamide as a self-sacrificed template, which have a high nitrogen content of 12.01 at.% and a specific surface area of 492.7 m 2  g −1 . The unique structure allows for exhibiting high specific capacitance of 250.64 F g −1 and excellent rate capability. [ABSTRACT FROM AUTHOR]

Abstract

In this paper, willow leaves were used to prepare activated carbons (ACs) by one-step pyrolysis with ZnCl 2 activation. The as-prepared AC-1-800 exhibits porous structure with high specific surface area of 1031 m 2 g −1 and a large pore volume of 0.66 cm 3 g −1 . As a supercapacitor electrode, it shows a good capacitive performance in 6 M of KOH aqueous electrolyte, such as the specific capacitance reaches 216 F g −1 at a current density of 0.1 A g −1 and the retention of specific capacitance is 97% after 1000 cycles at 2 A g −1 .
