Phosphatotungstic acid/titanium dioxide catalyst was prepared with TiO2 powder modified using impregnation with aqueous solution of phosphatotungstic acid, and characterised with H2-TPD, BET specific surface, TG-DTA, FTIR and UV-vis.

• 以磷钨酸水溶液湿法浸渍表面修饰TiO2制备了磷钨酸/二氧化钛复合催化剂；并进行了H2-TPR、BET比表面、TG-DTA、FTIR、UV-vis表征.
