The synthesis method for obtaining nanostructures of oxide compounds is described. Pore wetting of porous polycarbonate templates with the liquid precursor was followed by a two-stage thermal treatment to obtain single phase oxides as hollow and solid structures, with external diameter determined by the template pore size. The first thermal stage, a microwave assisted process, determines the shape of the structures. The second treatment at higher temperature allows to obtain the crystallographic structure of the compound. A variety of techniques are used to characterize the morphology and properties of these nanostructures. Applications of some nanostructures are described.
