제목 One-Pot Synthesis and Application of Magnetite Containing Mesoporous Carbon via Organic-Organic Self-Assembly
초록 We synthesized highly ordered magnetite containing mesoporous carbon using organic-organic self-assembly via one-pot synthesis process. Iron contents in mesoporous carbon were controlled from 0.5 to 10 wt% (to weight of the added resol precursor). With the content of Fe below 2.5 wt%, the mesostructures of magnetite containing mesoporous carbons were well retained with 2-D hexagonal symmetry, while the mesostructures were collapsed with the content above 5 wt% Fe. The particle sizes of magnetite in mesoporous carbon with 1 wt% Fe content were increased from 6.1 to 27.8 nm after carbonization at various temperatures from 600 to 900 oC. With the increase of Fe content to 10 wt% in magnetite containing mesoporous carbon, BET surface area and pore size were decreased 635.4 to 199.9 m2g-1 and 36.0 to 25.7 , respectively. We demonstrated the usefulness of these composites for the immobilization of drug (ibuprofen) and proved their easy manipulation by means of an external magnetic field.
