TL;DR: In this article, the effect of the cations and residual protons on the properties of heteropoly oxometalates was evaluated by the application of a variety of techniques, and the results showed that the cation has a profound influence on the structure, porosity, adsorptive properties, thermal stability, and catalytic properties.
Abstract: The cation is shown to have a profound influence on the structure, porosity, adsorptive properties, thermal stability, and catalytic properties of heteropoly oxometalates. Such salts are frequently found to be nonstoichiometric, with the cations being accompanied by residual quantities of protons. The effect of the cations and residual protons on the aforementioned properties is evaluated by the application of a variety of techniques.
