Supercapacitive properties of polyaniline/hydrous RuO2 composite electrode

A composite electrode based on polyaniline (PANI) and hydrous RuO 2 is prepared by electrochemical deposition of PANI onto hydrous RuO 2 (PANI/RuO 2 ) and its supercapacitive properties are investigated using cyclic voltammetry. The specific capacitances of PANI/RuO 2 and hydrous RuO 2 electrodes ar...

Zusammenfassung:	A composite electrode based on polyaniline (PANI) and hydrous RuO 2 is prepared by electrochemical deposition of PANI onto hydrous RuO 2 (PANI/RuO 2 ) and its supercapacitive properties are investigated using cyclic voltammetry. The specific capacitances of PANI/RuO 2 and hydrous RuO 2 electrodes are determined to be 708 and 517 F g −1 at 5 mV s −1 , respectively. Simple electrodeposition of PANI on the hydrous RuO 2 can achieve comparatively greater capacitance values.
