One-step synthesis of hydrophobic fluorinated ordered mesoporous carbon materials

Abstract

A series of fluorinated ordered mesoporous carbon (FOMC) materials were prepared by a one-pot method. The FOMC materials were characterized by X-ray diffraction, N₂ adsorption–desorption isotherms, high-resolution transmission electron microscopy, Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. The FOMC materials have well-ordered mesoporous structures with large specific surface areas and uniform pore sizes. Contact angle analysis showed that the FOMCs were more hydrophobic than the corresponding unfluorinated parent material. Thus the incorporation of fluorine improved the hydrophobicity of the carbon materials. This method provides a fast and easy-to-scale-up method for producing ordered mesoporous carbon materials with high hydrophobicity.
