Studies on chromia/zirconia catalysts. 1. Preparation and characterization of the system

The preparation and characterization (chemical, textural, DTA, XRD, XPS) of chromium oxide/zirconia, of interest as hydrogenation catalysts, are reported. The support (obtained via ZrOCl{sub 2} hydrolysis) can be tailored in surface area from high (360 m{sup 2}g{sup {minus}1}) values, and in texture...
