原始语种摘要: Abstract(#br)Design and preparation of high N-doped content biomass-derived hierarchical porous carbon with appropriate pores size distribution and high electrical conductivity draw extensive research attention for supercapacitors. Herein, N-doped mesopore-dominated hierarchical porous graphitic carbons PG/PEI-C Ni and PG/urea-C Ni are successfully synthesized based on a facile “in-situ template catalyst formed-removed” method, in which the corresponding mixture of peach gum/polyethylenimine/NiCl 2 and peach gum/urea/NiCl 2 are treated with hydrothermal and carbonization process, respectively. As-prepared PG/PEI-C Ni and PG/urea-C Ni possess high N-doped content (8.7 and 8.4 at. %), high specific surface area (875.9 and 1161.4 m 2 g −1 ) and excellent electronic conductivity (10.08 and...
