In this work, O3activation was performed at 200 °C over two types of Ag/CeO2catalysts with nanocube- and nanorod-like morphologies, respectively. The O3-indcued surface Ox−species (“Ox−injection”) accelerated soot combustion over both catalysts temporarily. In contrast, the depletion of CeO2surface oxygen vacancies (Ce3+-VO-s) caused by ozonization conferred to long-term activation. Specifically, the ozonized nanocubic Ag/CeO2with low initial Ce3+content not only benefited more from the “Ox−injection”, but also exhibited good redox stability and high practical potential. Therefore, the combination of this catalyst with O3activation may result in efficient soot elimination in the particulate filters of vehicles.
