EXAMINATION OF HIGH-LOADED NICKEL CATALYSTS BY IR SPECTROSCOPY: EFFECT OF THE SUPPORT AND Pd ON SURFACE PROPERTIES

Article abstract of DOI:10.1135/cccc19922575

Activation of the ammonia molecule and subsequent adsorption of the NH2 fragment on the surface of the NiO + Pd/TiO2 catalysts, in contrast to NiO + PdSiO2 catalysts, was demonstrated by IR spectroscopy.The decrease in the NiO + Pd/TiO2 catalyst acidity was manifested in the higher catalyst stability in reductive amination of diethylene glycol to morpholine.
