Fund Project:

MnO_x/CeO₂/SiO₂ catalysts were prepared by the adsorption phase reaction technique and were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), and Raman spectroscopy. HRTEM showed that MnO_x and CeO₂ particles were uniformly coated on the surface of SiO₂. The XRD spectra showed that the intensity of the Mn₃O₄ diffraction peaks gradually decreased and then completely disappeared with the increasment of the CeO₂ content, which indicated that CeO₂ reduced the crystallinity of MnO_x and improved the dispersibility of MnO_x. Raman spectroscopy indicated that Mn ions on the surface of catalysts could enter into the lattice of CeO₂, replace oxygen ions, and form oxygen vacancies. With the increasment of CeO₂ content, the density of oxygen vacancies initially increased and then decreased. We used the catalysts for selective catalytic reduction (SCR) of NO_x with NH₃. The catalytic activity initially increased and then decreased with the increasment of CeO₂ content, similar to the change in the density of oxygen vacancies. Thus, the catalytic activity of the MnO_x/CeO₂/SiO₂ catalysts increases with increasing the density of oxygen vacancies.
