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.
