| Résumé : | A series of phosphomolybdic acid (5–20 wt % PMA) promoted zirconia–ceria (ZrO2–CeO2) mixed oxides were synthesized by an impregnation method and characterized by XRD, nitrogen adsorption/desorption, UV–vis DR spectroscopy, TPR/TPD, and 31P MAS NMR spectroscopy. NMR spectra revealed that the catalyst retained the Keggin structure of PMA even after calcination at 500 °C. The catalysts were screened for the solvent-free liquid-phase oxidation of benzyl alcohols using hydrogen peroxide as the oxidizing agent. The sample of 15 wt % PMA/ZrO2–CeO2 showed 85% conversion and 96% selectivity to the corresponding aldehydes. |
