摘要：
This work studied bulk catalysts for hydrogenation processes of a carbonyl group that have similar compositions and contain copper, zinc, aluminum, and oxygen but were obtained by different methods, such as calcination of a mixture of salts followed by reduction in a hydrogen flow and alkalinization of metal alloys. The effect of the chemical composition and synthesis conditions of such copper-containing catalysts on their surface morphology and textural properties has been studied. The levels of adsorption of hydrogen on the studied catalysts are obtained by combined simultaneous thermal analysis-mass spectrometry. The presence of individual forms of adsorbed hydrogen with different metal-hydrogen bond energies is shown. An explanation for the difference in the adsorption properties relative to hydrogen is provided.
