Well‐defined core–shell Fe 3 O 4 @poly 4‐vinylpyridine‐ co ‐divinyl benzene (Fe 3 O 4 @P(4VP‐DVB)) magnetic polymer microspheres have been synthesized with the aid of strong hydrogen‐bond interactions between magnetic cores and functional monomers, as reported by Ge Wang et al. in their Full Paper on page 1160 ff. Au nanoparticles were embedded into the outer shell of as‐synthesized composite microspheres through reduction of HAuCl 4 to finally form the Fe 3 O 4 @P(4VP‐DVB)@Au nanostructure, which exhibited high catalytic activity, facile magnetic recoverability, and high stability for the reduction of 4‐nitrophenol.
