Abstract

Aluminum–magnesium layered double hydroxide (LDH) was obtained for the first time using the product of reaction between water and aluminum preliminarily activated by Ga–In eutectic alloy. This by-product of the reaction for hydrogen production was used as a reagent in the proposed hydrothermal synthesis of MgAl-LDH and allowed obtaining a material with a structure and properties similar to LDH synthesized by the conventional co-precipitation method. Supported palladium catalysts prepared using synthesized LDHs were highly selective in the aqueous-phase hydrogenation of furfural to furfuryl alcohol, probably due to modification of palladium with gallium introduced from the eutectic alloy at the stage of aluminum activation.
