Dawson structure heteropoly

The reducibility of type-I polyoxometalates, notably the Keggin, Wells-Dawson, and Lindqvist (hexametalate) structures, to mixed-valence heteropoly blues was well established in the 1960s and... [Pg.663]

In general, the structure of the heteropolyacids possesses a certain contribution of microporosity, and the pseudoliquid behavior that allows the adsorption of alcohol on the external surface and within the tertiary structure of heteropoly compounds (see Table 5.1). The abnormally high Ns of the fosfomolybdic Wells-Dawson acid is attributed to the presence of ethanol derived species, modifying the pore structure of the HPA. In fact, previous investigations demonstrated that the number of surface acid sites is directly influenced by the hydration water because fiilly... [Pg.87]
