摘要：

High surface area Co(OH)(2) nanosheets were prepared via cathodic electrodeposition and their electrochemical performance was investigated using cyclic voltammetry and charge-discharge tests. A specific capacitance as high as 1047.3 F g (1) was obtained in aqueous 1 M KOH within the potential range of -0.3 to 0.5 V (vs. Ag/AgCl) at the scan rate of 10 mV s (1), suggesting the potential application of the prepared nanosheets in electrochemical supercapacitors. Result of this Letter showed that galvanostatic cathodic electrodeposition can be recognized as a facile method for the preparation of porous and high surface area Co(OH)(2) sheets.
