In situ spectroscopic investigation of a Pd local structure over Pd/CeO₂ and Pd/MnO_x–CeO₂ during CO oxidation

Abstract

<italic>In situ</italic> X-ray absorption fine structure (XAS) and diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) experiments were performed to elucidate the effect of the Pd local structure on low temperature CO oxidation activity of Pd/CeO₂ and Pd/MnO_x–CeO₂.
