- Abstract
- Titania-pillared clay (Ti-PILC) as a catalyst support exhibited peculiar physicochemical characteristics compared to that of titania for the reduction of NO by NH,. The morphological variation of Ti-PILC was examined with respect to the preparation method. For the freeze-dried Ti-PILC, the development of needle-like crystallites, which may reveal the formation of a "house-of-cards" structure by delamination of Ti-PILC, has been observed. Ti-PILC catalyst contains high surface acidity examined by NH, TPD. Without the impregnation of WO3 and MoO3, on V2O5/Ti-PILC catalyst as a promoter, the catalyst exhibits competitive NO removal performance to a commercial V2O5-WO3/TiO2 catalyst. In addition, Ti-PILC catalyst also exhibits the strong sulfur tolerance mainly attributed to the unique pore structure of the catalyst.
