Abstract：

A　series　of　Mn-Ce　mixed-oxide　catalysts　supported　on　carbon　nanotubes　(CNTs)　were　prepared　for　the　first　time　and　used　for　the　selective　catalytic　reduction　of　NO　with　NH3.　Mn(0.4)-Ce/CNTs　catalysts　with　loading　from　0.6%　to　1.8%　(molar　ratio)　in　our　tests　showed　more　than　90%　NO　conversion　at　120-180　degrees　C　at　a　high　space　velocity　of　42,000　h(-1).　Transmission　electron　microscopy　confirmed　that　the　particle　size　of　Mn-Ce　mixed　oxides　supported　on　CNTs　was　2　to　4　nm.　BET　result　indicated　Mn-Ce　mixed-oxide　catalysts　obtained　enlarged　surface　area　and　pore　volume　which　was　beneficial　to　the　catalytic　activity.　(C)　2013　Elsevier　B.V.　All　rights　reserved.
