Synthesis and characterization of carbon nanotubes–TiO2 nanocomposites

Carbon Nanotubes and Carbon Nanotubes/Metal Oxide Heterostructures: Synthesis, Characterization and Electrochemical Property

“…They observed that the dispersion of pristine CNTs was more stable when the TiO 2 nanoparticles had been produced in the presence of the CNTs (in situ) compared with the simple mixing of the two materials. Upon reducing the amount of TiO 2 with respect to CNTs, Jitianu et al obtained a thin but rather irregular and partial coating of TiO 2 on CNTs [154,155]. Typically, the thickness of the coating can be controlled by various parameters, such as the reaction time [156], the reaction composition, and the choice of metal precursor [157].…”

“…Typically, the thickness of the coating can be controlled by various parameters, such as the reaction time [156], the reaction composition, and the choice of metal precursor [157]. For instance, in the case of TiO 2 , the use of titanium tetraisopropoxide (TTIP) produced irregular coatings [154,158], while tetraethoxy orthotitanate (TEOT) [154] or tetrabutoxy orthotitanate (TBOT) [157,159] enabled a more uniform deposition. The sol-gel process was sometimes carried out under reflux [156], or with the aid of ultrasonication [160], microwave [161], or magnetic agitation [162], in order to enable faster and simultaneous nucleation resulting in a more homogeneous coating.…”

Preparation and Performance of TiO2-ZnO/CNT Hetero-Nanostructures Applied to Photodegradation of Organic Dye

“…Nevertheless, these techniques are not easy and require specialized equipment. However, with the sol-gel method it is possible to obtain a homogeneous and effective coating for photocatalytic performance 16 . The objective this study is to obtain the TiO 2 -ZnO/CNT nanocomposite and use it as a catalyst for removal of methyl orange dye in solution.…”

Characterization and Photonic Effect of Novel Ag-CNT/TiO2Composites and their Bactericidal Activities

“…[7][8][9][10][11][12] In particular, Fullerenes and carbon nanotubes (CNT) have attracted considerable attention of late, as a result of their remarkable photoelectrical and mechanical properties, in addition to their other composites that possess intrinsic properties as materials exhibiting cooperative and/or synergetic effects. [13][14][15] Current synthesis and characterization of these nanomaterials can yield much more advanced colloidal photocatalytic nanoparticulate systems, which will allow enhanced photocatalytic activities. When TiO2 is coated on the CNT, the combination of large specific surface area will increase, binding to bacteria and viruses.…”
