Abstract: SYNTHESIS AND CHARACTERIZATION OF alpha-ZIRCONIUM (IV) HYDROGENPHOSPHATE CONTAINING METALLIC COPPER CLUSTERS. The alpha-zirconium (IV) hydroggeriphosphate (alpha-ZrP) has received great attention in the last years due to its properties like ion exchange, intercalation, ionic conductivity and catalytic activity. This work reports a method to produce metallic copper clusters on alpha-ZrP to be used as catalysts in petrochemical processes. It was found that the solids were non-crystalline regardless of the uptake of copper and the reduction. The specific surface area increased as a consequence of the increase of the interlayer distance to accept the copper ions between the layers. During the reduction, big clusters of copper (0,5-11mu) with different sizes and shapes were produced.
