For　Au-ceria　catalysts　prepared　by　deposition-precipitation　method,　catalytic　performance　of　water　gas　shift　reaction　was　studied　in　different　La　loadings.　In　the　complete　doping　range,　ceria　retains　with　its　cubic　fluorite　structures.　BET,　XRD,　H2-TPR,　HRTEM　studies　showed　that　La　doping　can　improve　the　activity　of　Au-ceria　catalyst　by　stabilizing　ceria　and　modifying　its　morphology.　In　addition,　the　test　of　catalyst　stability　evaluation　also　proved　a　better　stability　performance　of　Au-ceria　catalyst　can　be　realized　by　appropriate　La　doping.　©　Springer　Science+Business　Media,　LLC　2007.
