AbstractCrOx/CeO2 catalysts supported on porous silica sphere have been prepared and characterized by N-2-BET, XRD, XPS, H-2-TPR and NH3-TPD methods. The effects of the molar ratio between CrOx and CeO2 in the catalysts for NOx selective catalytic reduction with ammonia were studied. It was indicated by the results that high NOx conversion (98%) could be obtained by the catalyst with proper Cr/Ce molar ratio (25/75) at 150 degrees C (W/F = 0.25 g s/cm(3)). The result might be contributed to the redox property and NH3-chelate ability of the CrOx-CeO2 binary oxide in the catalysts. (C) 2010 Elsevier B.V. All rights reserved.
