Charge storage in carbon nanotube-TiO2 hybrid nanoparticles

Journal Article


Abstract


  • "Multi-walled carbon nanotubes (MWNTs) were directly deposited onto Ni modified TiO2 particles using chemical vapour deposition (CVD). These novel hybrid nanostrucured MWNT/TiO2 composites were characterised by scanning electron microscopy (SEM), revealing a novel hybrid structure wherein the CNT growth sprouted from the TiO2 particles and thermogravimetric analysis (TGA) that revealed a carbon content of 8%. Electrochemical methods were used to determine capacitance values as high as 146 Fg(-1) using acetonitrile containing 0.1 M tetrabutylammonium perchlorate as electrolyte. An energy density and power density of 21 Wh kg(-1) and 10 kW kg(-1) respectively were obtained. (C) 2012 Elsevier B.V. All rights reserved."
