Three new Dawson-type HPCs:K14·24H2O,K15H3·26H2O and K15H3·27H2O were synthesized for the first time.They are tungstophosphoric and molybdotungstophosphoric HPCs substituted by Ni or Cu.The intermediate product K10...
The Cs0.1Cu0.2HXPVAs0.2Mo10Oy and Fe0.12HXPVAs0.3Mo11Oy catalysts were prepared by impregnation method and characterized by FT-IR and TPR.The propane oxidation on the catalysts were carried out in a continuous flow fi...
In this paper,the phosphotungsten heteropoly acid catalytic membrance supported on porous titanium plate was prepared by dissolving the heteropoly acid in organic solvent then impregnating it on porous titanium plate....
