Nanoengineering of Metal Organic Frameworks for Applications in CO2 Capture, Drug Delivery, and Electronic Devices

Metal organic frameworks (MOFs), an emerging class of crystalline nanoporous materials, have recently caught attention for their unique properties such as high surface area, large pore volume, high uniform and permanent porosity, and ease of chemical tenability to introduce additional physical, chemical, or electrical properties. MOFs constructed from inorganic and organic pieces: metal ions and organic ligands, which play the role of linking metal nodes, respectively. Chemical versatility comes from the high variety of organic ligands (e.g. carboxylates, phosphonates) and metal centers (e.g. transition metals) available. Here, synthesis and characterization of MOFs for different applications, such as carbon dioxide capture, electroconducting materials, and drug delivery will be studied. Currently, one of the heightened global concerns is increasing CO 2 concentration which is argued to be a factor in rising global temperature and climate change. 4 Carbon capture and storage technologies show promise in this field, with research currently focused on large CO 2 emissions sources such as coal fired power plants. Competitive CO 2 capture capacities were obtained with MOFs as adsorbents at the CO 2 partial pressures expected in post combustion flue gas. However, important considerations such as the presence of moisture (5-7% by volume in the flue gas) and material regenerability requirements should be accounted for when designing an efficient CO 2 adsorbent.
