摘要：

The adsorption of NO2 on anatase and deuteroxylated TiO2 is investigated by IR spectroscopy. It is established that NO2 reacts with the surface hydroxyl (deuteroxyl) groups of anatase to give nitrates and water molecules (H2O, HOD and D2O) weakly bonded to the nitrates, while on the surface Lewis acidic-basic pairs of sites, NO2 disproportionates to NO+ and nitrates. The stability of the different adsorption forms is studied and their structures are discussed.
