Surface Area Enhancement Of Doped Carbon Materials Via Novel Freeze-Pore Methodology, Iris Denmark

Arkansas Women in STEM Conference

Supercapacitors are one of today’s growing means of alternative energy. They are portable, produce much higher capacitance than traditional capacitors, and operate under lower voltages than that of batteries. Herein, we have synthesized a series of supercapacitor materials from sodium lignosulfonate, otherwise known as lignosol, which are co-doped with phosphorus and nitrogen. The materials are synthesized utilizing a green and time-efficient microwave irradiation process. Subsequently, these materials have been optimized by utilizing a novel process by which surface area and electrochemical properties is enhanced by freezing of their porous surface. Materials undergoing this method have shown significant increase in BET …
