✦ Synopsis

In this paper is described the synthesis of silica microspheres of low dimensionality, that is, with diameters ranging from ca. 200 to 450 nm. The structure and essential features of these materials have been studied by electron microscopy and analysis of isotherms of physical adsorption and, in contrast of the previously established, the presence of a mesoporous structure within the silica spheres has been unambiguously demonstrated.

ZnO nanodomains embedded in bimodal mesoporous silica (UVM-7) materials with high Zn content (4 r Si/Zn r 30) have been synthesized by an one-pot surfactant-assisted procedure from a hydro alcoholic medium using a cationic surfactant (CTMABr = cetyltrimethylammonium bromide) as structural directing
