Tailoring of acido-basic properties and metallic function in catalysts obtained from LDHs for the hydrogenation of nitriles and of alpha-beta-unsaturated aldehydes

摘要

Ni~(2+), Co~(2+), Ru~(3+), and Mg~(2+)/Al~(3+) layered double hydroxides have been used as precursors of catalysts for the hydrogenation of acetonitrile, valeronitrile and cirtral. The acido-basicity and the metallic function of these materials are finely tuned up through the nature and the amount of the cations in the layers, and the activation conditions thus leading to active and selective catalysts.
