Reaction of carboxylic acids on CeO2(111) and CeO2(100)

Catalysis Today, 1996
The reactions of HCOOH and CH3COOH on CeO2(111) and CeO2(100) were studied using temperature programmed desorption (TPD) and high resolution electron energy loss spectroscopy (HREELS). The carboxylic acids were found to dissociate on both surfaces to form carboxylates.
