Modification of CrCeOx with Mo: improved SO2 resistance and N2 selectivity for NH3-SCR at medium–low temperatures

NH3-SCR at medium and low temperatures is an effective method for the removal of nitrogen oxides (NOx) in industrial furnaces. Chromium (Cr) and cerium (Ce) based catalysts exhibit excellent NH3-SCR potential at medium and low temperatures, but their sulfur resistance and N2 selectivity need to be f...
