Electrophoresis Coating of Titanium Dioxide on Aligned Carbon Nanotubes for Controlled Syntheses of Photoelectronic Nanomaterials

Using electrophoresis for TiO2 coating and photoexcited electrons for metal‐nanoparticle deposition, a facile method for the development of aligned coaxial nanowires of carbon nanotubes sheathed with TiO2 (see figure), and well‐defined TiO2 nanomembranes decorated with and without metal nanoparticles, is developed. The TiO2‐based nanostructures show fast photocurrent responses and possess unique photoinduced electron‐transfer properties.
