Boosting Catalyst Stability: Functional CeOx Nanoglues for Robust Atomically Dispersed Catalysts

Atomically dispersed catalysts (ADCs) hold immense promise for maximizing atom utilization and enhancing catalytic efficiency. However, their susceptibility to aggregation and leaching under harsh reaction conditions presents a significant challenge.

This study explores the utilization of functional CeOx nanoglues as a robust anchoring strategy for stabilizing ADCs. These nanoglues effectively address the stability issue by providing strong metal-support interactions, preventing the aggregation and detachment of single-atom catalytic sites.

Key highlights:

• Enhanced Stability: CeOx nanoglues act as 'nano-anchors,' firmly securing atomically dispersed metal atoms and preventing their migration and agglomeration.* Improved Catalytic Performance: The stable anchoring of metal atoms on the CeOx support ensures the availability of active sites, leading to enhanced catalytic activity, selectivity, and durability.* Potential Applications: This innovative approach holds significant potential for diverse catalytic applications, including but not limited to, fuel cells, pollution control, and fine chemical synthesis.

Exploring the Mechanism:

The study delves into the underlying mechanism responsible for the enhanced stability and performance of ADCs facilitated by CeOx nanoglues. Characterization techniques provide insights into the nature of metal-support interactions, revealing the crucial role of CeOx in preserving the atomic dispersion of catalytic sites.

Future Directions:

This research paves the way for developing highly stable and efficient ADCs. Future research will focus on optimizing the composition and morphology of CeOx nanoglues to further enhance their anchoring ability and tailor catalytic properties for specific applications.
