摘      要：Nitrogen doping could improve the performance of carbon materials in electrocatalysis,CO_(2) adsorption,and energy storage.[1]However,the control of the doping type and the amount of nitrogen(N)-doped in carbon materials in a simple and environmentally friendly way remains ***,we report a facile,multistage,self-assembly strategy for the synthesis of two-dimensional N-doped mesoporous carbon(2D NMC)by using graphene oxide(GO)as a structure-directing *** resultant 2D GO@NMCs rendered quantitatively controllable mesopores(8–25 nm).The 2D GO@NMCs rendered quantitatively controllablemesopores(8–25nm),high and controllable N content(up to 19 wt%),and the percentages of pyridine and pyridone/pyrrolic N atoms were as high as 49.9%and 35.3%,*** to these unique characteristics,the fabricated 2D GO@NMCs exhibited an ultrahigh surface-areanormalized capacitance of up to 90.6μF cm−2,which was much higher than the theoretical electrochemical double-layer capacitance of activated carbon(15–25μF cm−2).Moreover,our proposed multistage self-assembly strategy is versatile,and thus,could be extended to the synthesis of one-dimensional(1D)nanotubes@NMC and zero-dimensional(0D)nanospheres@NMC materials.
