报告摘要：

This presentation will discuss the efforts by our research groups at Northwestern University in exploring metal-organic frameworks (MOFs) for catalysis and separation/capture.

As hybrid materials derived from well-defined molecular building blocks, newly emerged porous materials such as MOFs are natural solid-state 3-D versions of supramolecules.  These materials have many of the desirable features of zeolites, such as high surface area and porosity, and can be similarly effective in size- and shape-selective catalysis. However, given the enormous diversity of potential structures and chemical functional groups that can be incorporated into the pores of MOFs, these porous materials have the potential to extend catalysis far beyond the realm of zeolitic chemistry to include enzyme-like behaviors such as adapted flexibility during catalysis, substrate pre-concentration effects, active-site isolation and protection, and tunable hydrophobicity.For example, recent developments in MOF synthesis have given rise to catalytically active materials with unprecedented stability and novel combinations of activities that were not observed in solution.  In addition, a combination of synthetic modulation and post-synthesis modification has allowed us to adddress the challenge of capturing multispeciated arsenic contaminants in water.
