• ) ternary oxide layer [19], which is based on a mixed Cu–O top layer with an alignment of Cu atoms along the [100] direction [20]. The Cu surface rows were shown to act as preferential adsorption sites for W3O9 nanoclusters. In all the above-mentioned studies, the W3O9 clusters were imaged with submolecular

• hollow SiO2 microtubes by exo-templating Tubular structures of ternary oxide CeO2/ZrO2@SiO2 were synthesized by using a multistep synthesis route. In the first step, dense fibrous mats of polystyrene (PS) fibers were obtained by an electrospinning process [15]. An inorganic/polymer composite, PS/silica
