Facile one-pot solvothermal synthesis of magnetic mesoporous carbon for the efficient adsorption of methyl orange.

A facile one-pot solvent thermal method was proposed to synthesize magnetic mesoporous carbon (MMC) using Fe(NO)·9HO as a precursor, Pluronic copolymer P123 as template, and chitosan as carbon source, and it was applied for the adsorptive remediation of methyl orange (MO). The characterization results of TEM, XRD, and IR showed that MMC consisted of graphitized carbon matrix and some black spherical particle mixture of FeO and Fe, and it was rich in hydroxyl and carbonyl groups. Besides, the effect of the content of Fe and the content of chitosan in MMC on the magnetism and adsorption performance of prepared material were investigated.
