For　Au-ceria　catalysts　prepared　by　deposition-precipitation　method,　the　catalytic　performance　of　water　gas　shift　reaction　was　studied　with　different　La　loadings.　In　the　complete　doping　range,　ceria　retains　with　its　cubic　fluorite　structures.　XRD,　HRTEM　and　UV-Vis-DRS,　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　that　a　better　stability　performance　of　Au-ceria　catalyst　can　be　realized　by　appropriate　La　doping.　The　Au/CL5.0　sample　with　5　at%　La　doping　showed　the　best　performance　in　WGS　reaction.
