英文摘要	A series of functionalized ordered mesoporous silica (OMS) materials were synthesized, characterized, and tested for their ability to uptake lignin-derived molecules such as guaiacol from dilute aqueous solution. A key observation was that OMS materials functionalized with hydrophobic groups have modest guaiacol uptake (<0.5 mmol/g), similar to what was observed with poly(styrene-co-divinylbenzene). Contact angle measurements show that samples with intermediate hydrophobicity in terms of wetting (between 60 and 100 degrees) display superior uptake properties. Oasis HLB, an example of such a material displays higher guaiacol uptake (0.8 mmol/g) as does as-made MCM-41, wherein the CTAB is left in the pores (AM-MCM-41, 0.7 mmol/g). Pore-expanded FDU-12 with a range of surface chemistries was synthesized and tested in an effort to generate a covalently grafted analogue of AM-MCM-41, however none of the materials showed uptakes above 0.35 mmol/g. Finally, other aromatic molecules such as vanillin, catechol, pyrogallol also showed high uptake (0.4 mmol/g or high) over Oasis HLB and AM-MCM-41. The findings suggest new routes for designing hybrid materials that can selectively remove lignin derivatives from dilute aqueous solutions.
