CeO2‐Encapsulated Hollow Ag–Au Nanocage Hybrid Nanostructures as High‐Performance Catalysts for Cascade Reactions

Abstract Inspired by bio‐enzymes, multistep cascade reactions are highly attractive in catalysis. Despite extensive research in recent years, it remains a challenge to promote the stability and activity of catalysts. Here, well‐defined core–shell structured Ag–Au nanocage@CeO 2 (Ag–Au NC@CeO 2 ) are designed by a simple and facile self‐assembly method. The results indicate that the Ag–Au NC@CeO 2 has glucose oxidase‐like activity and intrinsic peroxidase‐like activity at the same time. As expected, Ag–Au NC@CeO 2 hybrid nanomaterials exhibit cascade reactions activity. Moreover, the hybrid materials are promising to detect glucose without bio‐enzymes. This research has potential applications in biomedicine and biomimetic catalysis.
