Supercritical water syntheses of CexTiO2 nano-catalysts with a strong metal-support interaction for selective catalytic reduction of NO with NH3

- CHFS route had resulted in highly dispersed and strongly interacted (SMSI) CeO2 over the TiO2 support.
- SC-CexTiO2 catalysts showed superior SCR activity with broad operation temperature windows.
- SMSI had promoted enriched surface oxygen vacancies, facilitating the formation NO2 and nitrite species for SCR process.
- SMSI lowered the NH3 oxidation ability of CeO2, extending the SCR operation temperature window for SC-CexTiO2 catalysts.
- We expect to shed some lights on the development of advanced SMSI catalysts for SCR application.
