抄録

A Co (catalyst)-Ti-coated silicon foil on which carbon nanotubes (CNTs) are directly grown by thermal chemical vapor deposition (CVD) with/without H2 and using different temperatures/volume flow rates of NH3 is optionally pretreated with hydrogen-plasma. Thereafter the CNTs are treated with nitrogen-plasma, and a manganese-cobalt-zinc oxide film is deposited on the CNTs by radio frequency sputtering. For the CNT electrode, at the 100th cycle of potential cycling, its specific capacitance at a CNT growing temperature of 750°C is higher than those at 700 or 800°C and the higher the NH3 flow rate while growing CNTs, the higher the specific capacitance. Furthermore, the specific capacitance of the manganese-cobalt-zinc oxide/CNT electrode for the CNTs grown in 50 cm3 min−1 NH3 is higher than that without NH3.
