文摘
- •
CO could but H2 could not be oxidized over TiO2 under UV irradiation.
- •
Electron transfer behaviors of species adsorbed at TiO2 were characterized by gas sensing testing.
- •
Adsorbed CO donated electrons to TiO2 but adsorbed H2 accepted electrons from TiO2 under UV irradiation.
- •
Photocatalytic oxidation of species over TiO2 maybe depends on the electron transfer direction between species and TiO2.
