【 摘 要 】

The titanium dioxide nanoparticles with high purity and specific surface area were synthesized through an alkali-solution and acid-isolation method with titanium slag as raw material. As a catalyst support of V2O5-WO3-MoO3/TiO2 selective catalytic reduction catalyst, the high specific surface area TiO2 nanoparticles can improve the low temperature activity of the catalyst and enhance its resistance to sulfur poisoning.
