Abstract
Fourier transform infrared spectroscopy has been applied to the characterization of titania surface. The bands due to surface OH groups were observed to be more intense in the reduced titania than in the oxidized titania. The IR spectra of CO adsorbed on titania exhibited two C-O stretching bands, namely at 2187 and 2209 cm-1. The intensities were stronger in the oxidized titania.The 2187 cm-1-peak was attributed to CO coordinated to Ti4+5c (subscriptindicates the coordination number of the coordinatively unsaturated cation by oxygen ions), while the 2209 cm-1-peak due to the Ti4+4c…CO complex.
