Figure Abstract

Caption

Non-thermal plasma (NTP) efficiently activates lattice oxygen at asymmetric Ce-O-Co sites in the Ce0.8Co0.2O2-δ catalyst, enabling rapid soot combustion at low temperatures, with a maximum energy efficiency of 14.7 g kWh–1 — 49-fold higher than plasma alone (0.3 g kWh–1). NTP accelerates lattice oxygen activation to O* and the regeneration of the generated oxygen vacancies during the reaction by O atoms, O2, O3, O–, and O2– species, or adjacent lattice oxygen.
