Ferromagnetic hierarchical porous carbon (FHPC) with nickel particles embedded in the hierarchical porous carbon skeleton was synthesized. The hierarchical macro–mesoporous skeleton was formed by dissolving a salt template of Na2CO3and the ferromagnetic nickel particles were produced by in situ carbothermal reduction of nickel oxide. The saturation magnetization, remnant magnetization and coercive force of FHPC are 11.3emug−1, 2.3emug−1and 55.7Oe. The ferromagnetic property enables the magnetic separation of the FHPC from water. The surface chemical environments of the FHPC consist of different oxygen functional groups, like –OH, >COO and >CO groups, as well as a trace amount of aliphatic species of –CH3or [Formula: see text] structures. Dye separation performance of the FHPC was investigated using methylene orange, and the adsorption capacity was 0.16mgm−2with the adsorption kinetics constant of 2.2m2mg−1min−1, which is superior to that of magnetic carbon spheres.
