Fe-2(SO4)(3)/CeO2 composite oxide catalysts showed higher activity and enhanced N-2 selectivity compared to CeO2 and Fe-2(SO4)(3) catalysts, attributed to enhanced reducibility and surface acidity. Synergistic effect among Fe, Ce, and SO42- contributed to the improved NH3-SCR catalytic performance.
A series of Fe-2(SO4)(3)/CeO2 composite oxide catalysts were fabricated for the selective catalytic reduction of NOx by NH3 (NH3-SCR). Compared with CeO2 and Fe-2(SO4)(3 )catalysts, Fe-2(SO4)(3)/CeO2 exhibited much higher activity and enhanced N-2 selectivity. On the basis of the results of characterization, it can be seen that both the reducibility and the surface acidity of Fe-2(SO4)(3)/CeO2 have been enhanced remarkably, which is ascribed to the synergetic effect among Fe, Ce, and SO42-. In-situ DRIFTS research demonstrated that over Fe-2(SO4)(3)/CeO2, the generation of inactive nitrate was suppressed. Meanwhile, the adsorption and activation of NH3 was remarkably enhanced. Consequently, superior NH3-SCR catalytic performance was achieved over Fe-2(SO4)(3)/CeO2 catalyst.
