摘要

The oxide-zeolite (OXZEO) bifunctional catalysts have gained significant attention as an effective strategy to address the selectivity challenges in direct syngas conversion beyond Fischer-Tropsch synthesis (FTS). In OXZEO catalysis, the metal oxide component is mainly responsible for activating CO and H2, therefore determining the overall activity and product selectivity. Recent advances in sophisticated in-situ and quasi-in situ characterization techniques have shed light on the active sites of metal oxides and CO activation and its hydrogenation mechanism. This review focuses on these fundamental understandings, discussing the challenges and future directions.
