Selective Catalytic Reduction of NOx over Fe/TiO2 Prepared by F127- Template Method at Mid-Temperature


Yulin Li, Xiaojin Han, Yaoping Guo, Yaqin Hou, Zhanggen Huang and Qixiong Hou

A series of catalysts based on Fe/TiO2 were synthesized by template, impregnation, and co-precipitation methods for mid-temperature selective catalytic reduction of NO with NH3. The samples were characterized by Brunauer-Emmett- Teller (BET), X-ray diffraction (XRD), temperature programmed desorption (TPD) and Diffuse reflectance infrared Fourier transform spectra (DRIFTS). Among these catalysts, the sample prepared by template method exhibited the best catalytic performance. Analyses indicated that large specific surface area, good dispersion of active phase, and stronger NH4+ adsorption on Brønsted acid sites might be the main reasons for the high catalytic performance of Fe/TiO2 prepared by template method.
