Fabrication of MoO x -decorated In 2 O 3 nanotubes by electron-beam irradiation

We have proposed a structural transformation method in Mo-doped In 2 O 3 nanotubes (Mo-In 2 O 3 NTs), by electron-beam irradiation with a high-resolution transmission electron microscope. Uniform Mo-In 2 O 3 NTs have been presynthesized by a facile electrospinning method and calcined in air at 600 °C. As is expected, a large number of ultrafine nanoparticles gradually generate on the surface of Mo-In 2 O 3 NTs after a few minutes of exposure to 300 kV electrons, which are further confirmed to be the crystal structure of nonstoichiometric MoO x . This approach may be meaningful for us to design some novel nanostructures and has the potential to direct nanofabrication and emerging nanodevices.
