| 英文摘要 | the silica-based monolith exhibiting a hierarchical bimodal porous structure has been directly synthesized via lytropic mesophase. the hydrolysis and condensation of tetramethoxysilane (tmos) in the presence of poly(ethylene oxide)-block-poly(propylene oxide)-block-poly(ethylene oxide) (p123) and acetic acid results in silica monolith with msu-type mesoporous structure embedded in the skeleton of the interconnected macropore. the silica monolith with bimodal porous structure can separate benzene and phenol with high flow rate and low back-pressure. moreover, the chromatographic property of c-18-grafted silica monolith is investigated in the separation of aromatic molecules. our primary result shows that the silica monolith with interconnected macropore and msu-type mesopore is a promising packing material as stationary phase for high performance liquid chromatography.
