摘要
We report the synthesis of CoSx nanosheets from a 1,2-ethanedithiol/n-butylamine quasi-ionic liquid with the assistance of compressed CO2 at ambient temperature. The CoSx achieves a current density of 10 mA cm(-2) at an overpotential of 271 mV for the oxygen evolution reaction. Furthermore, our method is applicable to the fabrication of other transition metal chalcogenides.
