摘要：

Catalysts　of　Mn/TiO2　and　Mn-Ce/TiO2　prepared　by　coprecipitation　method　for　low　temperature　selective　catalytic　reduction　(SCR)　of　NO　with　NH3　were　investigated　in　this　study.　The　experimental　results　showed　that　co-precipitation　method　after　improvement,　the　NO　conversion　of　Mn-Ce/TiO2　catalyst　increased　sharply.　Meanwhile,　the　addition　of　cerium　has　significant　effects　on　the　catalytic　activity.　Characterizations　of　catalysts　were　carried　out　by　XRD,　BET　and　H2-TPR.　The　characterized　results　indicated　that　co-precipitation　method　after　improvement,　in　temperature　windows　150　to　300　°C,　showed　higher　NOx　conversion.　©　(2015)　Trans　Tech　Publications,　Switzerland.
