The adsorption effects of functionalized mesoporous materials on the pollutants, which includes organic compounds, dyestuff and heavy metal ions in waste water, biological macromolecules and medical molecules, and CO 2 and volatile organic gaseous, are summarized. The influence of the pore structure, modified groups and adsorption conditions of mesoporous materials on adsorption effect are also discussed. Moreover, the adsorption of the trace inorganic ions and strong polarity organic impurities in liquid crystal materials with functionalized mesoporous materials are introduced. Based on this,...
