Preparation and surface characterization of silica-supported ZrO2 : comparison of layered model systems with powder catalysts

Model supports consisting of a thin layer of SiO2 on a Si single crystal were used to study ZrO2/SiO2/Si model systems made by the same wet chem. prepn. methods as used in the prepn. of tech. catalysts. The results obtained with the models agree with those on ZrO2 catalysts on porous silica supports. [on SciFinder (R)
