Boosting low-temperature selective catalytic reduction of NOx with NH3 of V2O5/TiO2 catalyst via B-doping
文献摘要:
A series of B-doped V2O5/TiO2 catalysts has been prepared the by sol-gel and impregnation methods to investigate the influence of B-doping on the selective catalytic reduction(SCR)of NOx with NH3.X-ray diffraction,Brunauer-Emmett-Teller specific surface area,scanning electron microscope,X-ray photo-electron spectroscopy,temperature-programmed reduction of H2 and temperature-programmed desorp-tion of NH3 technology were used to study the effect of the B-doping on the structure and NH3-SCR activity of V2O5/TiO2 catalysts.The experimental results demonstrated that the introduction of B not only improved the low-temperature SCR activity of the catalysts,but also broadened the activity temperature window.The best SCR activity in the entire test temperature range is obtained for VTiB2..0 with 2.0%dop-ing amount of B and the NOx conversion rate is up to 94.3%at 210℃.The crystal phase,specific surface area,valence state reducibility and surface acidity of the active components for the as-prepared catalysts are significantly affected by the B-doping,resulting in an improved NH3-SCR performance.These results suggest that the V2O5/TiO2 catalysts with an appropriate B content afford good candidates for SCR in the low temperature window.
