Abstract

We describe the synthesis of novel nanocrystalline TiO₂ closely attached to BN nanotubes (BNNTs). The method involves the reaction of Ti ³⁺ with the oxidized radicals BN-H⁺ to form BN-Ti ⁴⁺ bonds first, and then in situ hydrolytic conversion of the attached Ti⁴⁺ into TiO₂. The designed reaction was carried out in a strongly acidic ethanol solution to ensure that the TiO₂ forms on the BNNT surface rather than in solution. We also report the improved photocatalytic reduction properties of TiO₂ when functionalized on BNNT surfaces and take advantage of the strong underlying electrostatic potential of the high-purity nanotubes. © 2010 Wiley-VCH Verlag GmbH © Co.
