Ordered mesoporous materials as adsorbents.

Environmental pollution, energy consumption and biotechnology have induced more and more public concerns. Problems imposed by these issues will circulate in the 21st century. Adsorption-based processes may lead to one of the most efficient routes for removal of toxic substances, energy storage and bio-applications. The fundamental and great challenge is developing highly efficient adsorbents. In this regard, ordered mesoporous materials (OMMs) may be the answer in the future. They possess intrinsic high specific surface areas, regular and tunable pore sizes, large pore volumes, as well as stable and interconnected frameworks with active pore surfaces for modification or functionalization. Such features meet the requirements as excellent adsorbents, not only providing huge interface and large space capable of accommodating capacious guest species, but also enabling the possibility of specific binding, enrichment and separation. As a result, these materials have been extensively studied as advanced adsorbents and hundreds of papers have been published since the millennium. In this Highlight, we will mainly summarize and outlook the development in pollution control, gas storage and bioadsorption by using OMMs as adsorbents.
