Modified ldh-supported au catalystssynthesis, characterization and catalytic performances in furfural liquid phase oxidation and hydrogenation

Abstract

This thesis focuses on the valorization of furfural, a biomass-derived compound, via oxidation and hydrogenation reactions. Thus, for the mentioned transformations in the previous sentence, gold-modified LDH-based catalysts were prepared: MgAlZr-LDH for oxidation and NiAlZr- LDH for hydrogenation. Besides these studies, a photooxidation study of glucose was also performed over the Au/NiAlZr catalyst, where light activation resulted in the improvement of catalytic performance. Characterization by IR, XRD, BET, SAA, SEM, TEM, and UV-visible techniques is performed in this work. It allows a correlation between their structure and catalytic performance, which provides insight into their mechanisms in the studied reactions.
