Abstract EN
Fluorine-containing hydrophobic mesoporous material (MFS) with high surface area is successfully synthesized with hydrothermal synthesis method by using a perfluorinated surfactant SURFLON S-386 template.
The adsorption properties of water vapor on the synthesized MFS are also investigated by using gravimetric method.
Results show that SEM image of the MFS depicted roundish morphology with the average crystal size of 1-2 μm.
The BET surface area and total pore volume of the MFS are 865.4 m2 g−1 and 0.74 cm3 g−1 with a narrow pore size distribution at 4.9 nm.
The amount of water vapor on the MFS is about 0.41 mmol g−1 at 303 K, which is only 52.6% and 55.4% of MCM-41 and SBA-15 under the similar conditions, separately.
The isosteric adsorption heat of water on the MFS is gradually about 27.0–19.8 kJ mol−1, which decreases as the absorbed water vapor amount increases.
The value is much smaller than that on MCM-41 and SBA-15.
Therefore, the MFS shows more hydrophobic surface properties than the MCM-41 and SBA-15.
It may be a kind of good candidate for adsorption of large molecule and catalyst carrier with high moisture resistance.
