Structure Control of V2O5/CNFs/Cordierite Monolith Catalyst and Its Catalytic Performance on NO Removal from Flue Gas

doi:10.3724/SP.J.1077.2012.11571

Abstract

Abstract: Carbon nanofibers (CNFs) were grown on Al₂O₃-coated cordierite monolith by chemical vapor deposition. The microstructure of V₂O₅ catalyst supported on cordierite monolith with CNFs layer was investigated by using scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray powder diffraction (XRD) and X-ray photoelectron spectroscope (XPS) techniques, as well as its activity for the selective catalytic reduction (SCR) of NO by NH3. The compressive strength of prepared CNFs/cordierite monolith composite was 34.46 MPa and the thickness of CNFs layer was 0.74 μm. The V₂O₅/CNFs/cordierite monolith catalysts had high NO removal activity in the temperature range of 150-250℃. When the CNFs yield and V₂O₅ loading were 12.5% and 1%, respectively, the NO conversion of the catalyst could reach 95% at 250℃.

Key words: cordierite monolith, carbon nanofibers, NO removal, catalyst
