X-ray diffraction, and Raman scattering study of nanostructured ZrO2-TiO2 oxides prepared by sol-gel.

Onthe other hand, the variation of the physicochemical prop-erties with decreasing the crystalline size to the nanoscale,opens up another way to tune the characteristics of thesesolids.Such modifications can be beneficial for catalysisand other applications, due to the increment of the surfacearea and the density of reactive sites.
