Preparation of homogeneous titania coatings on the surface of MWNTs

The aim of this work was to develop a controllable route to produce a stable and inorganic layer on the surface of multi-wall carbon nanotubes. Precursor compounds such as TiBr4, TiCl4, Ti(OiPr)(4), and Ti(OEt)(4) were used to cover the surface of carbon nanotubes (CNTs) under either solvent free or solution conditions. Various titania precursors were compared in the formation of homogeneous layers on the surface of CNTs. As-prepared titania coverages were characterized by transmission electron microscopy (TEM), high resolution TEM, scanning electron microscopy, electron energy loss spectroscopy, and Xray diffraction techniques. Results revealed that homogeneous coverage can be achieved in a controllable way. (C) 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
