摘要: We report on the synthesis and electrochemical properties of diamond grown onto vertically aligned carbon nanotubes with high surface areas as a template, resulting in composite material exhibiting double-layer capacitance well low impedance electrodes suitable for applications supercapacitor devices. contrast results from devices fabricated samples which differ both their initial substrates (Si Ti) final coatings, such boron-doped diamond-like (DLC). present first time conducting model non-doped DLC thin-films. All were characterized by scanning transmission electron microscopy Fourier transform infrared Raman spectroscopy. Our show specific 8.25 F g−1 (∼1 cm−2) gravimetric energy power 0.7 W h kg−1 176.4 kg−1, respectively, suggest that these diamond/carbon nanotube are excellent candidates fabrication.
