Hydrothermal preparation of carbon nanosheets and their supercapacitive behavior

Deflated-balloon-like and crumpled carbon nanosheets were prepared via a low-temperature hydrothermal carbonization of glucose at the two-phase interfaces. A low amount of glucose and a high amount of sodium dodecyl sulfate were found to be propitious to the formation of graphitic carbon nanosheets with low thickness. Their applications as supercapacitive materials were demonstrated.
