Resumen:

Oxidation features of Ce1-xLaxO2 and Ce1-xRuxO2 nanostructured solid solutions supported in Bi2Mo0.9Wo.1O6 were tested for carbon monoxide. Samples were prepared by citric acid route starting with La(NO3)3, Ru3C12O12 y C6H9O6Ce. The characteristics of structure, morphology, surface composition and surface area were determined by XRD, SEM and the BET method for surface area measurement. Also catalytic activity of samples was studied as a function of composition. High Ce contents (>0.9) benefit CO conversion at lower temperatures. Ce-La and Ce-Ru mixed oxides are highly active in the CO oxidation. Regarding Ce-Ru compounds, they become active at lower temperatures than Ce-La compounds. © 2009 by Nova Science Publishers, Inc.
