摘要：
La modified TiO2 prepared by sol–gel method as the support of Fe–Mn/TiO2(xLa) catalyst significantly improved SO2 resistance. La inhibited the growth of TiO2 particle, and led to the obvious layered structure of TiO2 and more mesopores, which accelerated the decomposition of ammonium sulfate. The increase of Brønsted acid sites and the electron transfer between La and active components Fe and Mn in La doped catalysts inhibit the adsorption and oxidation of SO2 on the catalyst, thus improving the SO2 resistance.
