Abstract

A facile surface protected silica shell etching method for fabricating multifunctional Fe₃O₄@CeO₂–Pt@mSiO₂ composites is reported. These multifunctional materials possess large magnetization, open mesopores, and a stably confined but exposed catalytically active component. The unique structures showed high thermal stability, magnetic recyclability and catalytic activity in catalytic reactions.
