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.
