Structures and Properties of Ordered Nanostructured Oxides and Composite Materials

Ordered nanostructured oxides are materials in which nano-objects are arranged in an array with a defined periodicity. Among them, ordered mesoporous oxides (OMPO), such as TiO2, SiO2, and ZrO2 are considered for a wide range of technological applications due to their low-cost reproducible synthesis...
