Resumen

A new and straightforward method to prepare high surface area Cu-ZrO₂ catalysts is presented. This method considers a reflux treatment of commercial hydrous zirconia in the presence of a copper-containing NH₄OH solution. The method allows the stabilization of high surface area ZrO₂ supports with highly dispersed CuO throughout the support surface. It was observed that the addition of copper by this reflux treatment decreases the crystalline character of the ZrO₂ support and increases the surface area. The potential catalytic application of these materials is exemplified with the CO oxidation and methanol reforming reactions.
