Preparation and Adsorption Properties of Microporous ...

The layered material RbxMnxTi2-xO4 (x = 0.75) was pillared with silica. The Rb ions were first exchanged with n-alkylammonium ions (CnH2n+1NH3, n = 6−18) to separate the interlayer space of the titanate, and then tetraethoxysilane was hydrolyzed between the layers. Burning off the organic parts resulted in silica pillared microporous solids with a surface area as large as 500−800 m2/g. The ...

Thin-layer chromatography - Wikipedia

Thin-layer chromatography (TLC) is a chromatography technique used to separate non-volatile mixtures. Thin-layer chromatography is performed on a sheet of an inert substrate such as glass, plastic, or aluminium foil, which is coated with a thin layer of adsorbent material, usually silica gel, aluminium oxide (alumina), or cellulose.This layer of adsorbent is known as the stationary phase.
