A　series　of　Au/CeO2-RE2O3　(RE　=　Nd,　Eu,　Sm,　Y)　catalysts　and　Au/CeO2-Y2O3　catalysts　with　different　Y2O3　contents　were　prepared　by　a　deposition-precipitation　method.　The　as-prepared　catalysts　were　investigated　by　N-2　adsorption-desorption,　X-ray　diffraction,　H-2　temperature-programmed　reduction,　and　Raman　spectroscopy,　and　the　catalytic　performance　was　evaluated　using　water-gas　shift　(WGS)　reaction.　The　results　showed　that　the　catalyst　activity　and　stability　are　obviously　enhanced　with　the　addition　of　Y2O3,　and　the　best　one　was　found　to　be　the　sample　with　Ce/Y　molar　ratio　equal　to　35.　This　catalyst　shows　the　highest　structural　stability　and　a　large　amount　of　surface　oxygen　vacancies,　and　the　interaction　between　gold　and　the　support　is　also　greatly　enhanced.
