| Abstract: | A series of Au/CeO2
catalysts has been prepared with CeO2 of varying surface areas and
tested for low-temperature CO oxidation. With a higher surface area support,
the Au/CeO2 catalysts show a higher catalytic activity for CO
oxidation (0.175 molCO gAu-1 h-1 at
0 °C). Higher oxygen vacancies provided by the formation of solid solution of
AuxCe1-xO2-δ and higher CO
chemisorption sites related to Au species are
responsible for the enhanced activity. |
