Nanostructured anatase TiO2 microtubes doped by Zr(IV), Hf(IV) and Mo(VI)

The nanostructured Zr-, Hf-, and Mo-doped anatase TiO2 microtubes has been synthesized via a template solgel method on a carbon fiber. The correlation between synthesis conditions of materials and their structure and morphology was investigated in detail by means of scanning electron microscopy, small-angle X-ray scattering, transmission electron microscopy, and Raman spectroscopy. Electrochemical behaviour of the materials as Li-ion batteries anodes was investigated by galvanostatic charge/discharge cycling.
