Selective Oxidation of Glycerol with O₂ Catalyzed by Fluorine-Modified CuNiAl Hydrotalcite

Abstract

A fluorine anion modified CuNiAl hydrotalcite (CuNiAl-LDH (F-)) was prepared for the selective oxidation of glycerol (GLY) using O2 as oxidant. It was found that the obtained catalyst with typical layer structures of hydrotalcite compounds was an effective heterogeneous catalyst in GLY oxidation. Under the present conditions, the main product was the C3 oxygenated products of primary alcohol glyceric acid (GLYAC). The highest conversion of GLY reached 32.0% with 58.1% of the selectivity to GLYAC.
