Abstract

Facile synthesis of ZnO nanorod core and polypyrrole shell arrays by electrochemical constant current deposition mode is reported. The effects of electrosynthesis parameters for polypyrrole (PPy) shell and its hybridization with graphene oxide (GO) on the structure, morphology and electrochemical properties of the core-shell arrays were analyzed. The results indicated a synergetic effect towards improving the electrochemical properties by tailoring the interfacial surface in ZnO/PPy core-shell arrays. High retention ratio (66 %) and an increase in voltammetric charge stored at inner surface (80 %) were exhibited by the ZnO/PPy-GO core/hybrid shell arrays with respect to ZnO/PPy ones.
