摘　　要：In this work,we have reported the synthesis of a series of heterogeneous catalysts,viz.,[HMIm]_(3)[PW_(12)O_(40)]@MOF-Fe,[HMIm]_(3)[PMo_(12)O_(40)]@MOF-Fe,and[HMIm]_(4)[SiW_(12)O_(40)]@MOFFe,by a simple impregnation method.The catalysts were characterized by several techniques,such as FTIR,EDX,XRD,SEM,elemental mapping,and TGA.Among these materials,[HMIm]_(3)[PW_(12)O_(40)]@MOF-Fe had more acidic sites(confirmed by potentiometric titration)and high stability around 598℃(confirmed by TGA).The catalytic prospect of the materials was examined through selective acetalization of glycerol to solketal as a fuel additive under solvent-free and room-temperature conditions.[HMIm]_(3)[PW_(12)O_(40)]@MOF-Fe exhibited the highest catalytic activity among the three catalysts in terms of glycerol conversion(100%),solketal selectivity(100%),and solketal yield(100%).A recyclability study of[HMIm]_(3)[PW_(12)O_(40)]@MOF-Fe showed that the material could be reused for up to 7 cycles with insignificant loss in its catalytic performance.
