With the aim of designing and preparing the materials based on polyoxometalates(POMs)and the metal-organic frameworks(MOFs)toward desired applications,a facile approach was developed to incorporate the clusters of Mo7O24^6-(Mo7),a representative isopolyoxometalate,into the vacant cages of ZIF-8.Through the so-called strategy of building MOF bottles around the POM ships,the powdered crystals and crystalline membrane of Mo7@ZIF-8 were synthesized,respectively.The products were characterized by IR,PXRD,N2 adsorption,and SEM.The Mo7@ZIF-8 crystals could effectively adsorb malachite green(MG)from water,and the maximum adsorption capacity reached 1963 mg·g^-1.The Mo7@ZIF-8 crystals could also be used for selectively adsorbing MG from the mixed dye solution containing MG and methyl orange(MO).Moreover,the Mo7@ZIF-8 membrane exhibited the proton conductivity of 9.5×10^-2 S·cm^-1 at 75℃under 98%relative humidity. 展开更多
