文摘

The loading of Ce effectively improves the oxygen activation and NO oxidizability. The mesoporous silica shell promotes the dispersion of ceria and results in strong redox ability of samples. The sequential reaction including NO oxidation process is beneficial to enhance SCR reaction rate in fast SCR process.
