Abstract Scope |
A family of compounds which can be represented by the general formulae: (NH4)3-(1-x)Mo12(Sbx,Mo1-x)O40.nH2O where x is 1 to 0. For example at x= 1 we make (NH4)3Mo12SbO40.nH2O, at x=0.5 we make (NH4)2.5Mo12(Sb0.5,Mo0.5)O40.nH2O and at x =1 we make (NH4)2Mo12MoO40.nH2O using the same synthetic procedure except varying the amount of Sb2O3 in the method. All these compounds are isomorphous and have exactly same XRD pattern and can only be differentiated by FTIR, crystal morphology, chemical analysis and extent of ion exchange. Ion exchange selectivity of (NH4)3Mo12SbO40.nH2O was very similar to ammonium 12-molybdophosphate :i.e. very high selectivity for Cs+ and Tl+ cations. Compounds obtained with different value of x in (NH4)3-(1-x)Mo12(Sbx,Mo1-x)O40.nH2O showed very distinct morphology. These compounds can be precipitated as large aggregates which can be flowable and suitable for additive manufacturing. These compounds are multifunctional and could find applications in catalysis and membrane sensors and membrane filtration. |
