Ti-containing SiO₂ nanotubes (TiSNTs) were firstly synthesized via a sol-gel and co-polycondensation method. After that, a family of Mn doped TiSNTs (Mn/TiSNTs) catalysts with various Mn loading were prepared via the co-precipitation method. When Si/Ti molar ratio was more than 5, a worm-like tubular morphology was clearly observed. The NH₃-TPD (NH₃-temperature programmed desorption) results show that the Ti doping into the skeleton of the silica nanotubes greatly enhanced the acidic sites of the catalyst and promoted the adsorption and NH₃-SCR (selective catalytic reduction) activation on the surface of the catalyst. Meanwhile, the results of H₂-TPR (H₂-temperature programmed reduction) also show that Ti doping enhanced the redox ability of the catalyst and the capacity of oxygen storage. Moreover, the doped Mn species was beneficial for reducing the reaction temperature. The results of SCR of NO_x with NH₃ show the catalyst with Si/Ti molar ratios of 10 (Mn/Ti(10)SNT) exhibited significant catalytic activity, and the NO conversion rate remained over 90% in the reactive temperature range of 135 to 325℃.
