Title: Hierarchically Structured Manganese Oxide-Coated Magnetic Nanocomposites for the Efficient Removal of Heavy Metal Ions from Aqueous Systems

Authors: Eun-Ju Kim, Chung-Seop Lee, Yoon-Young Chang, and Yoon-Seok Chang

Journal: ACS Applied Materials & Interfaces (Impact factor: 5.008)

Abstract: In this study, hierarchical MnO2-coated magnetic nanocomposite (Fe3O4/MnO2) was synthesized by a mild hydrothermal process, and its application for removing heavy metal ions from contaminated water systems was examined. The as-prepared nanocomposite had a large surface area and high magnetic saturation value, which ensured its good sorption ability and convenience of separation. This nanocomposite was easily recovered and reused through consecutive adsorption–desorption experiments with the assistance of an external magnetic field. Overall, the findings propose that Fe3O4/MnO2 could be used as an effective recyclable adsorbent for heavy metal ions.
