摘要：

A　facile　＇one-pot＇　strategy　was　reported　to　synthesize　a　mesostructured　Co/ordered　mesoporous　carbon　(OMC)　composite　associated　with　a　direct　carbonization　process　from　resol,　cobalt　oxalate　and　triblock　copolymer　F127.　The　obtained　materials　were　investigated　by　X-ray　diffraction　(XRD),　transmission　electron　microscopy　(TEM),　N2　adsorption-desorption　and　magnetometer　measurements.　The　results　show　that　the　mesoporous　composites　with　a　low　Co　content　possess　an　order　2-D　hexagonal　(p6mm)　structure.　With　the　increase　of　Co　content,　the　order　structure　of　the　Co/OMC　was　gradually　broken　down.　The　surface　area　and　pore　volume　of　magnetic　OMC　will　increase　with　a　low　Co　conten,　but　they　will　decrease　with　the　continued　increase　of　the　Co　content.　The　cobalt-containing　carbons　exhibit　soft　ferromagnetic　behavior　at　ambient　temperatures　and　the　magnetization　parameters　can　be　adjusted　by　the　content　of　cobalt.
