The addition of MoO3 enhanced the activity of CeO2/TiO2 catalyst for the selective reduction of NOx with NH3. The MoO3-promoted CeO2/TiO2 exhibited higher activity than CeO2/TiO2 even in the co-presence of H2O and SO2. This is because the introduction of Mo to the Ce10Ti catalyst can inhibit the adsorption of H2O and SO2 as well as the formation of sulfate species on the catalyst surface, thus alleviating the poisoning effect of H2O and SO2.
