The synthesis of titanium dioxide nanoparticles from titanium slag and its use for low temperature SCR catalyst

Abstract

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.
