摘　　要：Novel polyoxometalate(POM)Pickering interfacial catalyst(PIC)was fabricated through loading(NH_(4))_(5)H_(6)PMo_(4)V_(8)O_(40)(PMo_(4)V_(8))on both alkyl and alkyl-amino groups functionalized silica nanoparticles.PMo_(4)V_(8)/SiO_(2)(C_(8)/C_(8)NH_(2)with molar ratio as 1:1)PIC system provided a new catalytic model for aerobic conversion of 5-hydroxymethylfurfural(5-HMF),as well as its recovery and product separation in H_(2)O/methyl isobutyl ketone(MIBK)biphase reaction.Balancing the ratio of PMo_(4)V_(8),C_(8)and C_(8)NH_(2)gave rise to variety in hydrophilicity and hydrophobicity for PMo_(4)V_(8)/SiO_(2)(C_(8)/C_(8)NH_(2)),which enhanced the transformation of 5-HMF to 2,5-diformylfuran(DFF)in H_(2)O/MIBK with 73.7%yield at 81.8%conversion than in H_(2)O or MIBK single phase.
