Superior capacitive characteristics of RuO2 nanorods grown on carbon nanotubes

---

A B S T R A C T
Carbon nanotubes (CNTs) were used as the electric double layer capacitor (EDLC) material and were
synthesized by using thermal chemical vapor deposition (TCVD). To enhance the EDLC capacity, the
ruthenium dioxide (RuO2) nanorods were grown on CNTs by using metal organic chemical vapor
deposition (MOCVD). The synthesized CNTs were the principal part and template, and the RuO2
nanorods were grown outwardly from CNTs. The increase of effective specific area between electrode
and electrolyte played an important role in enhancing the capacitance. Different concentrations of KOH
were used as electrolyte to measure the capacitance to find the variation of capacitance. Moreover, the
RuO2/CNT composites demonstrated a stable cycle life. The results showed that the RuO2/CNT
composites were a promising supercapacitor device material.
