Metal oxide/CeO₂ nanocomposites derived from Ce-benzene tricarboxylate (Ce-BTC) adsorbing with metal acetylacetonate complexes for catalytic oxidation of carbon monoxide.

ABSTRACT: Herein, a series of metal oxide/CeO₂ (M/CeO₂) nanocomposites derived from Ce-benzene tricarboxylate (Ce-BTC) adsorbing with different metal acetylacetonate complexes were prepared for CO oxidation under four different CO gas atmospheres. It was demonstrated that Cu/CeO₂ exhibited the highest catalytic activity and stability in CO oxidation. Remarkably, both O₂ selectivity and CO selectivity to CO₂ are 100% in most of the investigated conditions. Several analytical tools such as N₂ adsorption-desorption and powder X-ray diffraction, were employed to characterize the prepared catalysts. In addition, the excellent catalytic performance of Cu/CeO₂ in CO oxidation was revealed by H₂ temperature-program reduc
