Thermally stable and insoluble silver salts of 12-molybdophosphoric acid with varying amount of Agcations were prepared. XRD results indicated the presence of single phase of AgxH3xPMo12O40(0 < x < 3). FTIR and Raman results indicated that Ag was incorporated in the secondarystructure of Keggin ion. The catalytic conversion of ethanol increased in the order ofH3PMo > Ag2PMo > Ag1PMo > Ag3PMo. Pure H3PMo is highly selective to dimethyl ether formation;in contrast AgxH3-xPMo12O40 catalysts offered better ethylene selectivity. The pyridine adsorptionstudies revealed that increase of Ag incorporating led to increase the Lewis acid sites.
