Codeposition of colloidal platinum particles and iron chloride precursor on TiO2 for efficient catalytic oxidation of CO to CO2

Research output: Contribution to journalArticle

Abstract

Codeposition of metal chlorides with Pt colloidal nanoparticles on TiO2 followed by oxidation at 400 °C and reduction at 200 °C improved the activity for Pt-catalyzed CO oxidation with stoichiometric amount of O2. The highest activity was obtained when FeCl3 was used as the additive with the Fe/Pt ratio of 0.2. XAFS, X-EDS, FTIR, and catalytic studies revealed that the deposition of Fe species on the reduced Pt sites gave active sites, which exhibited CO oxidation with high efficiency.
