Simple Synthesis of Magnetic Mesoporous Carbons with High Surface Areas by Soft-template Method

Magnetic Fe-containing ordered mesoporous carbons （Fe/OMCs） with high surface areas and pore volume were synthesized through a simple soft-template route, wherein phenolic resin was used as a carbon precursor, triblock copolymer F127 as a template agent, tetraethyl orthosilicate （TEOS） as a silica precursor and hydrated iron nitrate as an iron source. The effects of carbonization temperature, loading degree of TEOS on the structural parameters of these Fe/OMCs were evaluated by X-ray diffraction （XRD） and Nz sorption analysis. The ordering, the specific surface area and the total pore volumes increased with the increase of carbonization temperature from 600 to 850 ~C. And the specific surface area and the total pore volumes increased with the increase of TEOS loading.
