Combined effect of nitrogen and oxygen heteroatoms and micropores of porous carbon frameworks from Schiff-base networks on their high supercapacitance

Combined effect of nitrogen and oxygen heteroatoms and micropores of porous carbon frameworks from Schiff-base networks on their high supercapacitance

简介：A rigid Schiff-base network was synthesized and at higher temperatures led to the nitrogen and oxygen heteroatoms-containing porous carbon frameworks (HPCFs) by structural evolution through a facile one-step molten salt method.  By tuning the synthesis temperature, the HPCFs-based electrodes can afford surprisingly high specific capacitances. More importantly, the combined effect of various types of nitrogen and oxygen surface functionalities and the pore structure of HPCFs on its high supercapacitive performance was studied.
