Abstract
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.
期刊介绍：
Protection of Metals and Physical Chemistry of Surfaces is an international peer reviewed journal that publishes articles covering all aspects of the physical chemistry of materials and interfaces in various environments. The journal covers all related problems of modern physical chemistry and materials science, including: physicochemical processes at interfaces; adsorption phenomena; complexing from molecular and supramolecular structures at the interfaces to new substances, materials and coatings; nanoscale and nanostructured materials and coatings, composed and dispersed materials; physicochemical problems of corrosion, degradation and protection; investigation methods for surface and interface systems, processes, structures, materials and coatings. No principe restrictions exist related systems, types of processes, methods of control and study. The journal welcomes conceptual, theoretical, experimental, methodological, instrumental, environmental, and all other possible studies.
