| Abstract | The photocatalytic reactivity of one monolayer of methanol on TiO2(110) was measured with the surface sum frequency generation vibrational spectroscopy in the C-H stretching range, which shows high photon energy dependence. The photocatalytic reactivity was systematically investigated for different active species on TiO2(110), dissociative adsorbed methanol at five-coordinated Ti sites (Ti-5c), methoxy without adsorbed methanol at Ti-5c sites, and methoxy O-b sites. The results show that the methoxy at Ti-5c sites has much higher photocatalytic reactivity than that of dissociative adsorbed methanol at Ti-5c sites, and the methoxy at O-b sites might be inactive. This work demonstrates that methoxy at Ti-5c sites is the most active species on TiO2(110) and suggests that effectively removing surface OH could enhance the photodegradation of surface organics. |
