Since the initial discovery of ordered mesoporous silica in early 1990s, considerable innovations were achieved regarding their synthesis, characterization and applications. One of the best outcomes of these intense research efforts is the development of a solid templating method called “nanocasting”, which is based on using mesoporous silica (or carbon) as a rigid template. This solid-to-solid replication...
Different cobalt loadings (3, 6, 12, 24wt%) were impregnated using the double-solvent technique on SBA-15 calcined at 500°C presenting a high specific surface area. The impregnated solids were stabilized at 450°C in the air. The impregnation of cobalt led to the incorporation of cobalt oxide nanoparticles in the mesoporosity of the SBA-15. The cobalt nanoparticles were easily reducible compared to...
