摘要：
In the present work, protonated titanate nanoribbons were prepared by hydrothermal treating of TiO2 in alkali solution, followed by a thorough acid washing. The protonated titanate nanoribbons were employed as novel support for MnOx species and MnOx/protonated titanate was studied as a promising catalyst for the low temperature NH3-SCR reaction. The maximal NO conversion of ca. 98% was achieved over MnOx/protonated titanate at 200 A degrees C under high GHSV of 50000 h(-1). The existence of both MnO2 and Mn2O3 as active Mn species on protonated titanate was confirmed by XPS analysis, which was responsible for the high deNO(x) activity of MnOx/protonated titanate in NH3-SCR reaction.
