Abstract
Abstract A Mg Al layered-double hydroxides (LDH) intercalated by sulphonato-salen-chromium(III) complex was used to the selective oxidation of glycerol (GLY) using 3% H2O2 as oxidant. The results revealed that the LDH hosted chromium complex was effective heterogeneous catalyst. And the main product was the C3 oxygenated products of secondary alcohol‐dihydroxyacetone (DHA). Under the optimal reaction conditions, the highest conversion of GLY reached 73.1% with 43.5% of the selectivity to DHA. Moreover, the catalytic performance remained after being recycled 6 times. In addition, the reaction probably involved an enzyme mimetic mechanism.
