Novel synthesis of Fe-containing mesoporous carbons and their release of ibuprofen

A simple route has been developed to synthesize magnetic Fe-containing mesoporous carbon by an incipient-wetness impregnation technique without using a solvent. The materials were characterized by using X-ray diffraction, N-2 sorption, X-ray photoelectron spectroscopy, transmission electron microscopy, and physical property measurements. The species of iron in the resulting carbons were metallic alpha-Fe and magnetite Fe3O4/gamma-Fe2O3. The ordering of the mesostructure, the specific surface area and the total pore volumes decreased with the increasing amount of FeCl3 used. The saturation magnetization strength could be easily adjusted by changing the amount of FeCl3 used in the synthesis. Ibuprofen (IBU) release behavior from the materials showed that the release rate of IBU increased with the increase of the order and loading degree.
