Nanorods, Nanowires and Nanobelts of Oxides

Using a thermal vapor deposition method, WO nanorods were produced [118]. These nanorods grew along the [001] axis and were believe to contain a large number of stacking faults in the (200) planes as shown by HRTEM images. 

Nanorods of oxide can also be made using a template. In this case, the morphology of the nanorods would depend on the shape of the template. For example, WO3 can grow in mesoporous silica MCM-41 which consists of an array of cylindrical pores without intercormections [119]. The growing orientation of the nanorods is variable. 

This property reflected a regular (non-cyUndrical) cross-section of the nanowires and allowed the scienhsts to carry out convergent beam electron diffraction, from which the structural symmetry of In203 can be determined.
