Insights into synergistic effect of chromium oxides and ceria supported on Ti-PILC for NO oxidation and their surface species study

- Synergistic effect between CrOx and ceria supported on TP were studied for NO oxidation.
- TPD results indicated NO and O2 were activated by CrOx and ceria, respectively.
- H2-TPR analysis suggested that CrOx undertook the main function in catalysis.
- The nature and stability of surface-bound species were investigated by in situ DRIFTS.
