This work reports a strategy to promote the low-temperature CO2 methanation on the Ni-based catalyst by tuning the surface oxygen vacancy and medium-strength basic sites of the CeO2 support and thus changing the reaction pathway. La species was introduced into CeO2 support and calcined at 600 degrees C (CeO2-La-600) to form a La-Ce-O solid solution...
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 b...
