AB - Thermal stability of the TiO2 SCR catalyst with WO3 loading was investigated in terms of structural and morphological analyses. The TiO2 catalysts with 10 wt% WO3 content and without WO3 were prepared, which were heattreated at 800oC for 5 h. It was found that the catalytic acidity was decreased by thermal degradation in the WO3-TiO2specimen that relatively less than the TiO2 specimen from FT-IR analysis. The phase transition of the TiO2 catalyst from anatase to rutile was increased by heat-treatment, and the percentage of the rutile phase was 28.4 % in the WO3-TiO2 and 22.9 % in the TiO2. A shell region of WO3 distinguished from a TiO2 particle was also observed in the grain boundary region, and the WO3 led to the suppression of grain growth. It could be confirmed that the suppression of grain growth can contribute to the improvement of catalytic properties for thermal stability more than the increase of anatase-rutile phase transformation which cause the reduction of the catalytic activity in the TiO2 SCR catalyst by the presence of WO3.
