Abstract：

The　structure　of　Cu2+-exchanged　Ti-pillared　sepiolite　(Cu-Ti-PILS)　and　original　sepiolite　(Sep)　were　characterized　by　N2-Asorption/desorption,　SEM,　XRD　and　XPS.　The　catalytic　performance　of　Cu-Ti-PILS　for　the　selective　catalytic　reduction　(SCR)　of　NOx　by　propene　was　also　studied.　The　results　show　that　pore　volume　and　specific　area　of　Ti-pillared　sepiolite　(Ti-PILS)　are　significantly　higher　than　that　of　Sep.　The　results　of　XPS　and　XRD　of　samples　indicate　that　there　are　co-exist　Cu+　and　Cu2+　in　Cu-Ti-PILS　as　a　reaction　activity　centre.　The　catalytic　tests　show　that　the　activity　of　Cu-Ti-PILS　is　higher　than　that　of　copper-based　acid-activity　sepiolite　(Cu-H-PILS).　The　lower　temperature　of　Ti-pillared　is　favorite　to　catalytic　activity　of　SCR　of　NOx.　The　content　of　Cu　ion　exchange　over　Ti-PILS　is　0.02　mol/L　as　the　best　result　for　the　SCR　of　NOx.
