The dispersion capacity of WO3 on the surface of titanium silicalite (TS-1) was evaluated by XRD and FTIR spectroscopy techniques. The dispersion capacity of WO3 on TS-1 in the region of the hydroxyl groups using 3726 and 3505 cm-1 wavenumber are 0.40 and 0.38 W6+/nm2 TS-1, respectively, while the dispersion capacity using bands in the framework region between 900-700 cm-1 wavenumber gave 0.40 W6+/nm2 TS-1. These values are in a good agreement with the result from XRD analysis, i.e. 0.35 W 6+/nm2 TS-1.
