SURFACE-PROPERTIES OF THE NI-CU-CR OXIDE CATALYST FOR DEHYDROGENATIVEHYDROLYSIS OF AMINES

Catalysts for dehydrogenative hydrolysis of amines, prepared by sorpti on of copper ions from a solution on a preformed Ni-Cr oxide system, w ere studied by Auger electron spectroscopy, and IR spectroscopy of ads orbed CO and NH3 probe molecules. It was shown that on adsorption copp er blocked the chromium ions in the Ni-Cr catalyst with concomitant st abilization as Cu+. The incorporation of copper into the Ni-Cr system increased the ability of nickel to reduce water with the formation of oxygen-containing complexes.
