Abstract：

A　novel　MnOx–TiO2　catalyst　with　hollow　silkworm　structure　was　synthesized　successfully　via　an　ethanol-thermal　strategy　by　using　activated　carbon　fiber　felt　as　template　for　the　first　time.　The　silkworm-like　MnOx–TiO2　catalyst　(MnTi)　exhibited　higher　NOx　conversion　in　the　whole　experimental　temperature　region　(90–330 °C)　under　a　high　space　velocity　of　36,000 h−1　in　comparison　with　the　common　MnOx–TiO2　catalyst　without　hollow　silkworm　structure　(MnTi-B).　The　excellent　catalytic　performance　of　MnTi　can　be　attributed　to　its　high　specific　surface　area,　large　content　of　active　surface　oxygen　species　(OS),　and　more　surface　acid　sites.　In　addition,　the　MnTi　catalyst　also　exhibited　excellent　resistance　to　water　or　SO2　poisoning.　©　2019,　Akadémiai　Kiadó,　Budapest,　Hungary.
