  • 摘要: 以聚甲基含氢硅氧烷(PMHS)和正硅酸乙酯(TEOS)为原料,在不同的PMHS:TEOS质量比条件下合成了一系列具有微/介孔硅基材料.N2吸/脱附表征显示该材料具有微/介孔双孔分布的结构特征和较高的比表面积,并且随着PMHS:TEOS质量比的变化而变化.其中,当PMHS:TEOS质量比为1:3时硅基微/介孔材料具有最大的比表面积,达到783m2·g-1.XRD表征结果显示,该材料是无定形材料.材料对二硫化碳(CS2)的吸附性能的研究结果表明,PMHS:TEOS质量比为1:3合成的硅基微/介孔材料对CS2的吸附量最大,静态吸附量达到762.76mg·g-1,动态吸附穿透时间达到35min.再生实验表明材料再生性良好,可重复使用.
    Abstract: Micro/mesoporous SiO2-based materials were synthesized with polymethylhydrosiloxane (PMHS) and tetraethoxysilane (TEOS) with different PMHS/TEOS mass ratios. The materials were characterized by N2 adsorption/desorption. The micropore volume was calculated by t-Plot method, and the miropore size distributions was calculated by DFT method. The characterization revealed that the synthesized materials had large specific surface area. The specific surface area changed with the PMHS/TEOS mass ratio. When the PMHS/TEOS mass ratio is 1:3, the materials reached the largest specific surface area of 783m2·g-1. Meanwhile, it was found that the SiO2-based materials had the bimodal pore structures (mircoporous and mesoporous). The XRDdiffraction patterns indicate that the micro/mesoporous SiO2-based materials are amorphous materials. The adsorption properties of the materials were investigated with carbon disulfide (CS2) as a probe molecule. The static adsorption results indicated that M3 had the highest adsorption capacity which was synthesized with the PMHS/TEOS mass ratio of 1:3. The equilibrium adsorption capacity of M3 reached 762.76 mg·g-1. Moreover, the dynamic adsorption properties of the materials were also investigated. Among these materials, M3 had the best dynamic adsorption property. The breakthrough time of M3 was 35min. Regeneration experiments indicated that the material had a good regeneration property.
