Catalytic Oxidation of n-Decane, n-Hexane, and Propane over Pt/CeO₂ Catalysts.

ABSTRACT: Pt species with different chemical states and structures were supported on CeO₂ by solution reduction (Pt/CeO₂-SR) and wet impregnation (Pt/CeO₂-WI) and investigated in catalytic oxidation of n-decane (C₁₀H₂₂), n-hexane (C₆H₁₄), and propane (C₃H₈). Characterization by X-ray diffraction, Raman spectroscopy, X-ray photoelectron spectroscopy, H₂-temperature programming reduction, and oxygen temperature-programmed desorption showed that Pt⁰ and Pt²⁺ existed on Pt nanoparticles of the Pt/CeO₂-SR sample, which promoted redox, oxygen adsorption, and activation. On Pt/CeO₂-WI, Pt species were highly dispersed on CeO₂ as t
