A new synthetic strategy has been developed for the facile fabrication of a N-doped porous carbon (NC-800) material via a facile carbonization of functionalized poly(vinylidene fluoride) (PVDF). The prepared NC-800 exhibits good specific capacitance of 205 F/g at 1 A/g and cycle stability (95.2% retention after 5000 cycles at 1 A/g). The adsorption capacity of NC-800 on methylene blue and methyl orange was 780 mg/g and 800 mg/g, respectively. The facile and economical method and good performance (supercapacitor and adsorption) suggest that the NC-800 is a promising material for energy storage and adsorption.

通过对功能化聚偏氟乙烯（PVDF）进行简便的碳化处理，开发了一种新的合成策略，用于轻松制备氮掺杂多孔碳（NC-800）材料。制备的NC-800在1 A/g电流密度下表现出205 F/g的良好比电容和循环稳定性（在1 A/g电流密度下循环5000次后保留率为95.2%）。NC-800对亚甲基蓝和甲基橙的吸附容量分别为780 mg/g和800 mg/g。这种简便且经济的方法以及良好的性能（超级电容器和吸附性能）表明，NC-800是一种有前途的储能和吸附材料。
