Abstract
Transformations of Pt/TiO2 catalyst between non-SMSI and SMSI states have been investigated by repeatedH2−O2 titration. The decline of capacity of H2 and O2 chemisorption and their reaction on Pt particles is accountable by reduction of superficial labile oxygen species in the temperature range of 298–573 K and an increase of surface oxygen vacancies on TiO2 above 573 K, respectively.
