Activity improvement of gold yolk–shell catalysts for CO oxidation by doping with TiO2

Abstract

Au, @ZrO2 yolk–shell catalysts were found to exhibit a surprisingly high activity in CO oxidation even though the gold particle size is about 15 nm. A further enhancement of the activity has been achieved by simply doping these materials with small amounts of TiO2 during synthesis. A comparison of the standard Au, @ZrO2 yolk–shell catalysts with the novel TiO2-doped Au/Ti, @ZrO2 shows significant activity enhancement, even though small amounts of TiO2 are present.
