A series of transition metal sulphonato-Schiff base complexes were intercalated into Mg-Al layered-double hydroxides (LDHs). The obtained catalysts were characterized by FTIR, XRD, N 2 sorption, SEM and elemental analysis, and then were used in the selective oxidation of glycerol (GLY) using 3% H 2 O 2 as an oxidant. It was found that their catalytic performances were closely related to the loading of active complexes, the Schiff base ligands and the metal centers of the catalysts, as well as
