NC vs. AC: Nitrogen-doped mesoporous carbon (NC) is prepared by heat treatment of mesoporous carbon under NH3 at 850 °C. Compared with KOH-activated mesoporous carbon (AC), NC shows catalytic activity towards sulfur reduction. Furthermore, under the same current rates, NC/S composite shows a higher discharge potential and capacity than the AC/S composite in an ionic-liquid electrolyte both at 25 °C and 50 °C.
