Magnetic Mesoporous Carbons Derived from in Situ MgO Template Formation for Fast Removal of Heavy Metal Ions.

ABSTRACT: In this paper, magnetic mesoporous carbon composites were prepared by calcination of the mixture of magnesium citrate and Fe₃O₄@SiO₂ in an inert atmosphere. A high content of Fe₃O₄@SiO₂ and MgO was in situ embedded in a carbon matrix. After removing the MgO template by diluted acid, the resulting material (Fe₃O₄@SiO₂@mC) was subjected to further H₂O₂ oxidation treatment. The formed oxygen-containing functional groups on the products provided plenty of active sites for the adsorption of analytes of interest. The obtained composites (Fe₃O₄@SiO₂@mC-H₂O₂) exhibited a mesoporous structure with a high specific surface area
