Multifunctional nanostructures based on porous silica covered Fe3O4@CeO2–Pt composites: a thermally stable and magnetically-recyclable catalyst system†
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.
