Significance

Photooxidation of alkanes using decatungstate W10O32 4- on a novel hydrophobically-organomodified SBA-15 as catalyst was described. The catalyst W10/C8-AP-SBA (W10=[W10O32 4-], C8 = octyl group, AP = 3-aminopropyl group) was prepared by treatment of C8H13Si(OEt)3 with SBA-15, grafting with 3-aminopropyl amine, acidification with CF3SO3H and ion exchange by decatungstate. W10/C8-AP-SBA showed photocatalytic oxidation activity for various alkanes under mild conditions to afford the corresponding ketones (7 examples, 28-97% conversion).
