title: Dramatic effect of redox pre-treatments on the CO oxidation activity of Au/Ce(0.50)Tb(0.12)Zr(0.38)O(2-x) catalysts prepared by deposition-precipitation with urea: a nano-analytical and nano-structural study.
abstract: Nano-structural and nano-analytical studies show that the dramatic difference in CO oxidation activity observed between two Au/Ce0.50Tb0.12Zr0.38O2-x samples prepared by deposition-precipitation with urea and further activated under oxidising or reducing conditions is due to the poisoning effect of a very thin layer of carbon grown on the pre-reduced catalyst.
