说明书摘要	This invention relates to the cleaning of flue gas released from various combustion processes, particularly a surface deposition NH3—SCR honeycomb catalyst and its preparation method. The catalyst is composed of framework material, TiO2, V2O5 and WO3, wherein the framework material is composed of clay, coal ash, mineral waste residue or their mixture. The mass fractions for framework material, TiO2, V2O5, and WO3 are 60 wt. % to 80 wt. %, 13 wt. % to 33 wt. %, 1 wt. % to 5 wt. %, and 0.1 wt. % to 2 wt. %, respectively. The nano V2O5—WO3—TiO2 particles were deposited on the surface of particle pore or honeycomb, and the performance of the catalyst could be greatly improved
