1. one kind based on TiO 2-SnO 2The SCR catalyst for denitrating flue gas of composite metal oxide carrier is characterized in that:

  • at nano-TiO 2-SnO 2On the complex carrier, load auxiliary agent WO 3And CeO 2, active component V 2O 5Common formation composite catalyst;

    Wherein, at described nano-TiO 2-SnO 2In the complex carrier, TiO 2Shared mass percent is 50-95%;

    In the composite catalyst that makes, TiO 2-SnO 2Mass percent be 83.5-94.5%, V 2O 5, WO 3, CeO 2Shared separately mass percent is respectively 0.5-1.5%, 4-10% and 1-5%.
