  • Publication number: 20130136860
    Abstract: A method of fabricating carbon nanotube arrays (CNTA) on an oxide catalyst layer is disclosed. In one embodiment, the oxide catalyst is a metal oxide. The metal oxide may be deposited on a substrate used as a support. The CNTA is grown on the oxide catalyst layer under conditions promoting CNT growth. CNT growth is dependent on temperature, concentration of oxidizing molecules and carbon availability. One embodiment of the method comprises depositing an oxide catalyst layer on the substrate, heating the catalyst layer at certain rates to the target temperatures, adding oxidation molecules for the pretreatment of the oxide catalyst layer, and growing the array on the substrate. The oxide catalyst layer may comprise a group VIII element.

  • Publication number: 20130065050
    Abstract: A method of dispersing a metal or metal oxide within a CNT or CNT array, comprising exposing the CNT or CNT array to a solution containing a metal compound in a non-aqueous liquid; and removing the non-aqueous liquid from the CNT or CNT array. Nanoparticles were homogenously deposited within millimeter-long carbon nanotube array (CNTA). After modified with nanoparticles, CNTA changes from hydrophobic to hydrophilic. The hydrophilic composite electrodes present ideal capacitive behavior with high reversibility. The novel, nano-architectured composite demonstrates strong promise for high-performance thick and compact electrochemical supercapacitors.
