摘要：

(Graph Presented) Limited holeliness: Core-satellite nanocomposite catalysts protected by a layer of mesoporous silica have been fabricated through the combination of simple sol-gel and etching processes. As superparamagnetic components are also incorporated, these composite structures are ideal recyclable catalysts.
