Pt dendrimer-like nanoparticles were in situ deposited on the magnetic Fe3O4@polydopamine core-shell composites due to the metal-binding ability and weak reducibility of polydopamine. Such core-shell-satellite catalyst structure endowed the Fe3O4@polydopamine-Pt catalyst with excellent magnetical recyclability, aqueous dispersity, and high catalytic performance for the catalytic reduction of 4-nitrophenol and its derivatives, and methylene blue. This catalyst could be reused for 12 cycles without losing its catalytic activity, indicating the high stability.
