Microflowers made of interconnected MnO₂ nanosheets have been successfully synthesized in a microwave reactor through a hydrothermal reduction of KMnO₄ with aqueous HCl at elevated temperatures in the presence of superparamagnetic Fe₃O₄@SiO₂ core-shell nanoparticles. Due to the chemical compatibility between SiO₂ and MnO₂, the heterogeneous reaction leads to the spontaneous encapsulation of the Fe₃O₄@SiO₂ core-shell nanoparticles in the MnO₂ microflowers. The resulting hybrid particles exhibit multiple properties including high surface area associated with the MnO₂ nanosheets and superparamagnetism originated from the Fe₃O₄@SiO₂ core-shell nanoparticles, which are beneficial for applications requiring both high surface area and magnetic separation.
