Biasini for help in measuring magnetic properties, and Prof. P. Feng, R. Liu, Prof. Y. Yan, and M. Sun for BET measurements.
Graphical Abstract
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. (see plot for performance in repeated cycles of 4-nitrophenol reduction).
