Construction and catalytic applications of advanced ceramic-supported single atoms

In the domain of novel catalyst design and application, single-atom catalysts (SACs) have attracted widespread interest due to their ability to provide high catalytic activity and maximize the utilization of active sites. Various support materials capable of effectively anchoring single metal atoms have been reported, among which ceramic materials have received notable attention due to their distinctive versatility. This work primarily aims to elucidate the unique role of typical ceramic carriers in anchoring, isolating metal atoms, and participating in catalytic reactions. Here, we will clarify the interaction between metal atoms and ceramic carriers to explain the stabilization of atomic metal sites and the rational adjustment of individual atomic geometry and electronic structures. Furthermore, a comprehensive summary of recent research progress in SACs, with particular emphasis on advancements in preventing the migration or aggregation of isolated metal atoms, has also been stated. Regarding applications, we review the utilization of ceramic-supported SACs in electrocatalysis, photocatalysis, and other catalytic reactions. Finally, we discuss the challenges and prospects of ceramic-supported SACs in this field.
