Copper Zinc Aluminate Synthesized by Sol‐Gel Method with Polyacrylic Acid as Catalysts for Glycerol Hydrogenolysis

This study describes the use of novel Cu/ZnO/ZnAl2O4/PAAH (PAAH=polyacrylic acid) hybrid nanomaterials for glycerol hydrogenolysis. Their elaboration by sol-gel process either in one step or two steps allowed to modulate their structural properties terms specific surface area, Lewis acidity, sizes and dispersion copper nanoparticles. The presence PAAH aluminium during synthesis particularly showed benefits metal-support interaction. characterization catalyst surfaces composition size nanoparticles establish structure-reactivity relationships. optimization reach remarkable conversions up 96 % with selectivity towards 1,2-propanediol 83 %. A recyclability also a possible reuse these catalysts after reactivation step.
