Photocatalytic selective aerobic oxidation of alcohols to aldehydes and ketones by HPW/MCM-41 in ionic liquids

Abstract: The selective oxidation of alcohols with molecular oxygen was efficiently completed in high conversion and selectivity using HPW/MCM-41 as a heterogeneous photocatalyst in ionic liquids, [bmim]PF6, [omim]BF4 and [hmim]BF4. Comparative studies on the catalytic properties of HPW/MCM-41, HPW to MCM-41 were carried out. Some important variables, e.g. the loading amount of HPW on MCM-41 and the effects of different ionic liquids were discussed in this work. [Copyright &y& Elsevier]
