| 英文摘要 | Simultaneously improving both NOx conversion and N2 selectivity in the selective catalytic reduction of NO by CO (CO-SCR) under O2-containing conditions is highly challenging because of the competitive reactions of NOx and CO with O2. Here, we demonstrate that the interfacial oxygen vacancies (IOVs) generated at the Co3O4-CeO2 heterointerfaces by ball-milling-induced strain can remarkably boost both NOx conversion and N2 selectivity in the temperature range of 100-400 degrees C. The Co3O4-CeO2-IOV catalyst achieved approximately 100% NOx con-version and 100% N2 selectivity (200-350 degrees C, 1-5 vol% O2, and 20,000 h-1); even under 10 vol% O2, it still showed good catalytic performance. The spectroscopy analysis and theoretical calculations reveal that compared with O2 activation, IOVs are more favorable for the rate-limiting step of NO adsorption and dissociation. This work provides an effective strategy to create IOVs within metal oxide composite catalysts using ball-milling -induced interfacial strain for improving CO-SCR performance. |
