Synthesis of ZnO/MWCNTs Nanostructure via Hydrothermal Method and its Electrochemical Capacitive Performance

Abstract:

The composites of ZnO/multi-wall carbon nanotubes (ZnO/MWCNTs) were efficiently synthesized via a simple hydrothermal method, and their capacitive properties were evaluated by cyclic voltammetry (CV) and galvanostatical charge/discharge tests, respectively. The resulting ZnO/ MWCNTs composite displayed net-like combined structure, in which the flower-like ZnO particles assembled by ZnO nanorods were entangled by the MWCNTs, Electrochemical investigation exhibited that the highest speciﬁc capacitance of 310 F g^-1 was obtained when the content of MWCNTs reached to 20%, compared to the ZnO (55 F g^-1) and MWCNTs electrode (17 F g^-1), showing the synergistic effect of ZnO and MWCNTs. The excellent net-like hybrid structure and the good conductivity of MWCNTs were considered to be responsible for its preferable electrochemical performances.
