Abstract
⺠The barrier for the 2nd O2 dissociation channel decreases with increasing TiO2 reduction state. ⺠The barrier for Ti interstitial diffusion decreases with increasing TiO2 reduction state. ⺠The shape of the O2-TPD peak(s) at â¼410 K depends on the crystal reduction state. ⺠The quantity of O2 desorbing at â¼410 K is non-linear to the crystal reduction state. ⺠Sub-surface defects such as Ti interstitials enable O2 adsorption on rutile TiO2(1 1 0).
