Abstract

Among the different possibilities to control the size, the shape and the spatial organization of nano-objects, one consists in the use of the ordered mesoporosity of silica matrices as nanoreactors for their synthesis. This strategy has been used to elaborate Prussian Blue Analogues (PBA) exhibiting photomagnetic properties. Since the synthesis of these nanocomposites begins with the obtention of mesoporous silica monoliths containing Co2+ ions, we focus in this paper on the effect of the quantity of Co2+ ions and the amount of surfactant on the nanostructuration of these monoliths.
