We synthesized highly ordered and magnetically separable ordered mesoporous carbons via one-pot synthesis process. With the content of Fe below 2.5 wt%, the mesostructures of magnetic mesoporous carbons have well-ordered 2D-hexagonal symmetry at 700 oC, while the mesostructures were collapsed with the content above 5 wt% Fe. BET surface area and pore size of the magnetite containing masoporous carbon with 1wt% Fe (1 wt% Fe-FDU-15) were 635.4 m2g-1 and 36.0 , respectively. The saturation magnetization value of 1 wt% Fe-FDU-15 after carbonization at 700 oC was 7.7 emug-1. On the other hand, BET surface area and pore size of 1 wt% Co- and Ni-FDU-15 were 700.0, 528.4 m2g-1 and 17.2, 36.4 after carbonization at 700 oC, respectively. The saturation magnetization value of 1wt% Co- and Ni-FDU-15 was 1.3 and 1.0 emug-1. We demonstrated the usefulness of these composites for the adsorption of amino acids (IBU, Phe) and proved their easy manipulation by means of an external magnetic field. |
