چکیده انگلیسی
We demonstrated here the crosslinked N-doped graphene (NG) can be rapidly prepared through a one-step burning process of graphene oxide. The doping process completed within 3Â minutes and the N content in the obtained NG reached to 5.6%. The obtained crosslinked NG shows mesoporous structure with relatively high specific area, large pore volume and various N types. As a supercapacitor, the resultant NG exhibits rapid diffusion of electrolyte ions and shows superior capacitive performance, excellent specific capacitance (317.5Â F/g at the current density of 1Â A/g) and high cycling stability (93% retention after 5000 cycles). The obtained results indicate that the crosslinked NG is a promising candidate for creating supercapacitors with high performance and relatively low cost.
