| Abstract | Reducible oxides as supports have been demonstrated to improve the activity of Pt catalysts towards water-gas shift (WGS) reaction. The Pt species anchored by the oxygen vacancies derived from these supports play as catalytic sites during low-temperature WGS reaction. Herein, we introduced CeO2 to modify TiO2 nanotubes (TiO2NT) and prepared CeO2-TiO2 hybid-nanotubes ((CeO2)(x)(TiO2)(1-x)NT, x=0.2, 0.4, 0.6) to confine Pt nanoparticles (NPs) as the efficient catalysts for the low-temperature WGS reaction. Pt NPs confined in (CeO2)(x)(TiO2)(1-x)NT catalysts exhibit higher WGS activity than that of the Pt NPs entrapped in pure TiO2NT (Pt-in-TiO2NT) and Pt/CeO2 catalysts throughout the entire reaction temperature range. Activity measurements coupled with the physicochemical characterization of catalysts suggest that the redox ability of PtOx species is positive correlated with WGS activity and oxygen vacancy adjacent to Pt (Pt-O-v) serves as the active site for H2O dissociation and CO oxidation in WGS reaction. |
