Abstract：

A　series　of　Ru/Sm2O3-CeO2　catalysts　were　prepared　by　using　a　co-precipitation　(CP)　method　and　characterized　by　XRD,　BET,　SEM,　H-2-TPD-MS,　H-2-TPR　and　CO　chemisorption.　The　activity　test　shows　that　ammonia　concentration　of　the　catalyst　with　7%　Sm　is　13.4%　at　10　MPa,　10,000　h(-1),　425　degrees　C,　which　is　21%　higher　than　that　of　Ru/CeO2.　Such　high　catalytic　activity　was　due　to　three　effects:　the　morphology　changes　of　catalyst,　electrodonating　property　of　partially　reduced　CeO2-x　to　Ru　metal　and　the　property　of　easily　hydrogen　desorption　derived　from　the　presence　of　Sm3+　in　ceria.　(C)　2011　Elsevier　B.V.　All　rights　reserved.
