Sulfur-doped mesoporous carbon thermal reduction of CS by Mg for high-performance supercapacitor electrodes and Li-ion battery anodes.

This paper demonstrates a facile method based on vapor-solid reaction between magnesium powder and carbon disulfide vapor to produce S-doped porous carbon. The property of the as-prepared carbon is tunable by varying the synthesis temperature. The sample synthesized at 600 °C shows the highest specific surface area, suitable for supercapacitor electrodes.
