Abstract

The vanadium oxide/reduced graphene oxide (V2O5/rGO) composite catalyst which determined the selective catalytic reduction activity (SCR) of NO with NH3 was prepared by a simple solvothermal method. The physicochemical properties of the catalysts were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman, X-ray energy spectrometer (XPS) and N2 sorption isotherm measurement (BET). Results of NH3-SCR showed that the NO conversion of V2O5/rGO catalyst could reach 54.3% at 100 °C. And the removal of NO increased to 74.6% when the temperature was up to 220 °C. By characterizing the microstructure and morphology of the V2O5/rGO catalysts prepared by in-situ growth and mechanical mixing methods, it was further shown that V2O5 nanoparticles were highly dispersed and in situ growth on the rGO surface. Based on X-ray energy spectrometer, V2O5/rGO catalyst had good low temperature denitrification performance due to the chemical adsorption oxygen and low-valent vanadium oxide contained in V2O5/rGO catalyst, which was beneficial to the redox reaction between V2O5 and graphene.
