Abstract
The IR and UV—vis diffuse reflectance spectra of mesoporous WO3/ZrO2 are discussed and a scheme proposed for the acid site structure on the WO3/ZrO2 surface. The high Brönsted acidity of WO3/ZrO2 (H0 ≤ −11.38) can be explained by the formation of large zirconium polytungstate species such as [≡ Zr61/2+W66+O202−]− H+ on the WO3/ZrO2 surface.
