• usually the inverse miniemulsion technique has to be applied. Here, water soluble precursor compounds (e.g., Ti- or Si-glycolates, Zr or Ce-salts) for sol–gel synthesis and, if desired, templating surfactants, such as CTAB, are dissolved in water, acting as the dispersed phase. After miniemulsification

• using microwave irradiation. Results and Discussion The ZnO nanoparticles obtained through the sol–gel synthesis (see section Experimental) are shown in Figure 1a and Figure 1b as transmission electron microscopy (TEM) micrographs. The low-resolution TEM micrograph exhibits spherical nanoparticles with
