Molten salt synthesis of hierarchical porous N-doped carbon submicrospheres for multifunctional applications: High performance supercapacitor, dye removal and CO2 capture

Hierarchical porous N-doped carbon submicrospheres (HPNCs) are synthesized by a facile molten salt method. The as-prepared HPNCs not only exhibit high supercapacitance performance, but also possess ultrahigh adsorption performances for chemical dyes and CO2.277
