Abstract

Nano-scale rods of titania and tungsten oxide were fabricated on metallic titanium and tungsten substrates by heat-treatment in vucuo. The surface structure and morphology were characterized by Thin-film X-ray diffraction analysis (TF-XRD) und scanning electron microscopy. The TF-XRD analysis indicated that the thermal treatment in vacuo (6.7 × 10-2 Pa) gave TiO2 (rutile; PDF#21-1276) and WO3 (PDF#20-1324) nano-scale rod arrays. The mechanism of the nano-scale rod array formation was explained by the structure matching due to topotaxy and the crystal growth habit.
