Abstract

Abstract Nonporous heteropoly oxometalates are shown to be capable of absorbing polar molecules into their bulk structures while retaining their properties as solids. The results from photoacoustic FTIR, X-ray diffraction and sorption measurements are employed to illustrate this feature. In contrast, certain of the monovalent salts of heteropoly oxometalates may be prepared with microporous structures. Nitrogen adsorption-desorption isotherms, X-ray diffraction, diffusivities, sorption capacities and reactions of selected probe molecules illustrate this microporosity and provide an explanation for the source of this pore structure.
