Abstract

The growth of TiO₂ nanorods on a WC-Co substrate by metalorganic chemical vapor deposition has been observed by SEM and TEM. The nanorods diameter and length were about 50-100nm and 0.5-2μm, respectively. Nanorod growth was observed at 500°C, while mostly particles were deposited at 600°C and a thin coating was formed at 400°C. It appears that the presence of cobalt catalyzes the directional growth of TiO₂ and NH₃ enhances this growth behavior. In the presence of NH₃, thinner and longer nanorod growth was observed.
