Controlled synthesis of core/shell magnetic iron oxide/carbon systems via a self-template method
Journal of Materials Chemistry
A sol-gel assembly process was developed for the synthesis of magnetic core/carbon shell materials with porous networks. Fe(CO) 5 was assembled into the pore channels of mesoporous silica via a sol-gel method at 18 C, by using the block copolymer F127 as the template and Fe(CO) 5 as an additional precursor. At this temperature, the magnetic precursor Fe(CO) 5 was pre-organized into hydrophobic cores of micelles by self-assembly of F127. In the subsequent carbonization of the assembly under andoi:10.1039/b912057b fatcat:e6zh6du44be2lhsogre2aao2lq
