“…They therefore exhibit different advantages and disadvantages. A number of review articles have been published in the last decade describing progresses on their preparations, properties, and applications [12][13][14][15][16][17][18]. It can be easily found that the problems of both the swelling or shrinkage of organic monoliths in some solvents and the tedious fabrication procedures of the silica-based monoliths always encumber the researchers and limit the applications.…”

Hybrid organic-silica monolithic columns, regarded as a second generation of silica-based monoliths, have received much interest due to their unique properties over the pure silicabased monoliths. This review mainly focuses on development in the fields of preparation of hybrid monolithic columns in a capillary and their application for CEC and capillary liquid chromatography separation, as well as for sample pretreatment of solid-phase microextraction and immobilized enzyme reactor since July 2010. The preparation approaches are comprehensively summarized with three routes: (i) general sol-gel process using trialkoxysilanes and tetraalkoxysilanes as coprecursors; (ii) "one-pot" process of alkoxysilanes and organic monomers concomitantly proceeding sol-gel chemistry and free radical polymerization; and (iii) other polymerization approaches of organic monomers containing silanes. The modification of hybrid monoliths containing reactive groups to acquire the desired surface functionality is also described.

“…The materials used for a monolithic bed are classified into two categories: silica monoliths 1 and polymer monoliths. 2,3 Silica-based monolithic columns have some advantages over polymer-based ones, including a well-controlled pore structure, good mechanical strength, and high column efficiency, especially for small molecules.…”

“…[34] The image is typical of the bicontinuous monolithic morphology. [29,[35][36][37] The SEM measurements suggest that the coral like network is preserved when Au is incorporated in the monolith by either method (Fig. 3b and 3c).…”

The impregnated Au-containing monolith was found to be less active than the thiol functionalized Au-containing material, attributable to the low metal surface area of the Au nanoparticles. The reaction on the thiol functionalized Au-containing monolith was found to depend strongly on the type of oxidant used: tert-butyl hydroperoxide (TBHP) was more active than H 2 O 2, likely due to the thiol induced hydrophobicity in the monolith.
