The application of selective catalytic reduction with ammonia (NH3-SCR) technology urgently requires catalysts good performance to control nitrogen oxide (NOx, x = 1, 2) emissions, and structural analysis such is necessary crucial elucidate the catalytically active sites. Thus, we prepared molybdenum (Mo)-doped CeO2 achieve a substantial leap in performance. results revealed that emergence Ce3+–O–Ce3+ units induced by Mo doping achieved low-energy barrier activation NH3 molecule, which transformed dominant reaction mechanism thus led much better SCR Furthermore, designed tungsten (W)-doped same amount as found exhibited almost activity trend Mo-doped catalysts, further confirmed pivotal role units. This study provides basic theoretical foundation for design ceria-based efficient NOx removal.

The development of efficient technologies for the synergistic catalytic elimination NOx and chlorinated volatile organic compounds (CVOCs) remains challenging. Chlorine species from CVOCs are prone to catalyst poisoning, which increases degradation temperature fails balance selective reduction with NH3 (NH3–SCR) performance. Herein, chlorobenzene has been originally demonstrated by using phosphotungstic acid (HPW) as a dechlorination agent collaborate CeO2. conversion was over 80% at 270 °C, N2 selectivity reached 95% 270–420 °C. HPW not only allowed chlorine leave inorganic but also enhanced Bro̷nsted acidity NH4+ produced in NH3–SCR process can effectively promote low temperatures. remained structurally stable reaction, resulting good water resistance long-term stability. This work provides cheaper more environmentally friendly strategy address poisoning reaction offers new guidance multipollutant control.
