Novel oxidative-acidic bifunctional catalyst of tungsten-phosphate modified silica-titania

A novel oxidative-acidic bifunctional catalyst of tungsten-phosphate supported silica-titania was successfully synthesized and characterized. Different tungsten amount was impregnated into silica-titania followed by phosphoric acid treatment via sol gel method. The impregnation of WO3 and PO4 3 - in...
