“ Attractive” catalyst: Molybdenum oxide nanoparticles have been incorporated into a mesoporous silica shell and coated on silica‐coated magnetite nanoparticles for use as a magnetically separable heterogeneous epoxidation catalyst. This catalyst, which has a low Mo loading of 1 mol %, can be recycled and reused six times in the epoxidation of cis ‐cyclooctene with no major loss of activity (see picture).
