Abstract: | RuO2 nanostructures were synthesized by heating Ru nanoparticles in air at 280°C using Cu as catalyst. The Ru nanoparticles were
prepared by the pyrolysis of ruthenium precursors in a vacuum using multi-walled carbon nanotubes as templates. The RuO2 nanostructures grew radically with diameters of 50–150 nm, and lengths of 0.5–2.0 μm. The growth of nanostructure mainly
depends on the dispersivity of Ru nanoparticles on MWNTs. The electrochemical property of these nanostructures was studied
by cyclic voltammetry.
