Multiple-metal　catalysts　(Ni-Mn-Ce-K/bauxite)　for　Water-Gas　Shift　(WGS)　reaction　were　prepared　by　impregnation,　and　the　catalytic　structure　and　properties　were　investigated　by　N2　physical,　XRD,　H2-TPR,　and　CO-TPD.　The　results　indicated　that　the　addition　of　7.5%　CeO2　improved　the　activity　of　the　WGS　reaction　obviously,　and　also　increased　the　specific　surface　area　and　pore　volume　of　the　catalysts.　The　addition　of　CeO2　decreases　the　reduction　temperature,　enhanced　the　adsorption　and　activation　of　H2O,　and　improved　the　adsorption　content　of　CO.　Besides,　active　sites　were　not　changed　and　the　number　of　active　sites　on　catalysts　did　not　increase　obviously.　©　2008　The　Chinese　Society　of　Rare　Earths.
