New approach for synthesis of Mo-containing LDH based catalysts

Molybdate inserted layered double hydroxides (LDHs) were prepared by anion exchange in their aging step of synthesis under hydrothermal conditions. These materials were characterized by X-ray diffraction, chemical analysis, N2 physisorption, DR UV–vis and Raman spectroscopy. The solids as prepared showed interesting chemical, structural and textural properties. They proved high catalytic activity for the oxidation of sulfur-containing organic molecules and anthracene by hydrogen peroxide under gentle reaction conditions. The results were compared to those obtained over Mo-containing LDHs prepared by conventional ion exchange.
