Abstract
The tungstophosphoric heteropolyacid (H5PW11TiO40) contained titanium was prepared and then characterized by FT-IR, UV, XRD and TG/DSC analysis, which revealed that the H5PW11TiO40 heteropolyacid was Keggin structure and one H5PW11TiO40 heteropolyacid molecule contained fifteen crystal water molecules (H5PW11TiO40·15H2O). And the tungstophosphoric heteropolyacid (H5PW11TiO40) contained titanium could be used as a green catalyst for cleaner reactions.
