Abstract Various methods for the preparation of metal oxide catalysts for environmental control purposes are described. These include coprecipitation, sol-gel, and impregnation, and are used to prepare mixed oxide catalysts of the types SnO2-MO2 (M=Ce or Zr), SnO2-Ln2O3 (Ln = lanthanide), Ln-doped CeO2, Cr (VI)-doped SnO2, and Cu(II)-doped SnO2. The aggregation in stable colloidal sols of SnO2, CeO2 and ZrO2 is dependent on the concentration of the metal oxide. Techniques for the characterisation of these catalyst materials include gas adsorption, X-ray diffraction, and TEM/EDXA.
