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.encatalytic,Characterization by IR, XRD, BET, SAA, SEM, TEM,,between their ,mechanisms,Modified ldh-supported au catalysts: synthesis, characterization and catalytic performances in furfural liquid phase oxidation and hydrogenationThesis
