Abstract

The nanocomposites of multiwalled carbon nanotubes (MWNTs)/titania (TiO₂) were prepared by direct growth of TiO₂ nanocrystals onto carboxyl-modified MWNTs under hydrothermal condition. The structure and morphology of TiO₂ nanocrystals growing on MWNTs were tuned by adjusting acidity, reaction temperature, and reactant ratio. The results showed that a uniform layer of anatase TiO₂ nanocrystals on MWNTs could be achieved at proper synthesis parameters. Flowerlike assemblage of rutile TiO₂ nanocrystals was dispersed on MWNTs. The formation mechanism of MWNTs/TiO₂ nanocomposites was further provided.
