Abstract

An active Pd/MgAlOx catalytic system providing selective formation of benzyl alcohol in an industrially important reaction of benzaldehyde hydrogenation was synthesized and studied using X-ray diffraction, scanning and HAADF-STEM electron microscopy, nitrogen and CO2 adsorption, TPR and CO pulse chemisorption methods. Additional advantages of these catalysts include the possibility of regeneration and reuse. For the first time, palladium catalysts based on layered double hydroxides (LDHs), synthesized by the mechanochemical method, have been obtained. It has been shown, that the solid-phase mechanochemical method is effective and more environmentally friendly, and the catalysts, synthesized by this method, are not inferior to samples, synthesized by the traditional coprecipitation method, in their textural characteristics, basicity, activity and selectivity.
