Highly porous zirconia with defined particle morphology can be prepared by impregnation of spherical activated carbon as an exotemplate with a zirconia nanoparticle sol. The resulting zirconia spheres show a particle size distribution between 0.2 and 0.4 mm and exhibit high specific surface areas and specific pore volumes up to 104 m2g–1 and 0.56 cm3g–1, respectively. Addition of a triblockcopolymer...
Zirkoniumdioxid ist nicht nur thermisch und meachnisch sehr stabil, sondern kann auch mit großer spezifischer Oberfläche und großem spezifischen Porenvolumen hergestellt werden. Dadurch ist es als Katalysatorträger interessant. Die Herstellung von Partikeln mit größeren Abmessungen gelingt über Exotemplatsynthese unter Verwendung von Aktivkohle mit kugelförmigen Partikeln. Der Zusatz eines Endotemplats...
