Effect on Catalytic Activity and Characterization of Content of V₂O₅-WO₃ by Chemical Vapor Deposition

Abstract:

The honeycomb cordierite, loaded with carrier TiO2 by atmospheric pressure chemical vapor deposition (APCVD), was to produce the V2O5-WO3/TiO2 catalyst by impregnation process. The paper presents the effect of the content of V2O5 and WO3 on the catalyst by analyzing the microstructure and ingredients of catalyst by means of SEM, BET, XRD and EDS. The results show that the BET of the catalyst composed by 2.1%V2O5-8.2%WO3/TiO2 is 854.33m²•g-1 , Its hole area is 73.56 m2•g-1, the average pore size is 9.8nm,the main phase is Mg2Al4Si5O18,anatase-TiO2 and WO3.The distribution of vanadium monomer on the carrier TiO2 prepared by APCVD is monolayer, and minim particle is acicular. The NO removal rate (ηNO/%) of the catalyst with 2.1%V2O5 and 8.2%WO3 achieves 98.9%.
