XPS Characterization of CeO2 Catalyst for Hydrogenation of Benzoic Acid to Benzaldehyde

The CeO 2 catalysts for hydrogenation of benzoic acid to benzaldehyde were characterized by X-ray photoelectron spectroscopy (XPS). The results indicate the catalyst deactivation is due to the coke formation and the valence changes of Ce over the catalyst.
