| Summary: | Metalorganic frameworks (MOFs) have recently attracted intense research interest because of their permanent porous structures, large surface areas, and potential applications as novel adsorbents. The recent progress in adsorption-based CO

capture by MOFs is reviewed and summarized in this
critical review
. CO

adsorption in MOFs has been divided into two sections, adsorption at high pressures and selective adsorption at approximate atmospheric pressures. Keys to CO
2
adsorption in MOFs at high pressures and low pressures are summarized to be pore volumes of MOFs, and heats of adsorption, respectively. Many MOFs have high CO

selectivities over N

. Water effects on CO
2
adsorption in MOFs are presented and compared with benchmark zeolites. In addition, strategies appeared in the literature to enhance CO
2
adsorption capacities and/or selectivities in MOFs have been summarized into three main categories, catenation and interpenetration, chemical bonding enhancement, and electrostatic force involvement. Besides the advantages, two main challenges of using MOFs in CO
2
capture, the cost of synthesis and the stability toward water vapor, have been analyzed and possible solutions and path forward have been proposed to address the two challenges as well (150 references).

| Bibliography: | Jian Liu is currently a Postdoctoral Research Associate at the Pacific Northwest National Laboratory (PNNL), USA. His research interests include carbon dioxide capture, metalorganic frameworks (MOFs) synthesis and applications, gas adsorption fundamental and applications, and materials chemistry. Jian received his Bachelor of Engineering degree from Beijing Institute of Technology in 2003 and then in 2006 he obtained a Master of Engineering degree from Chinese Academy of Sciences. He earned his PhD in Chemical Engineering from the Vanderbilt University in May 2011. Before joining PNNL, Jian was working with Professor M. Douglas LeVan at the Vanderbilt University on adsorption equilibrium and mass transfer in MOF adsorbents. Jian has won the 2011 AlChE Separation Division Graduate Student Research Award in Adsorption and Ion Exchange. Dr Liu has published over 15 peer reviewed papers and presented several talks in four consecutive AlChE Annual Conference. He is also a member of the AIChE and the Sigma Xi Society. 2 among other basic science studies of key importance for designing CO Jun Liu is a Laboratory Fellow at the Pacific Northwest National Laboratory and a leader for the Transformational Materials Science Initiative. He is also a Fellow for the American Association for the Advancement of Science. In the past, he has served as a Pacific Northwest National Laboratory Fellow, senior research staff for Sandia National Laboratories and Lucent Bell Laboratory, Department Manager for the Synthesis and Nanomaterials Department, Sandia National Laboratories, and Thrust Leader for Complex Functional Nanomaterials for the Center for Integrated Nanotechnologies, Sandia National Laboratories. He is recognized for his research in functional nanomaterials and their application for energy and environment. He has received an R & D 100 Award, and he was named 2007 Distinguished Inventor of Battelle. He has over 200 publications and many invited review articles in leading technical journals. capture and sequestration systems. He has over 220 publications and presentations at international conferences on his research. B. Peter McGrail is a staff member at PNNL for over 28 years and has attained the position of Laboratory Fellow, the highest level of scientific achievement at the laboratory. He directs a wide variety of research projects in greenhouse gas emission management, energy efficiency technology development. Dr McGrail manages the Zero Emission Research & Technology Center, which is conducting groundbreaking work on the reactivity of molecular water solvated in supercritical CO Praveen K. Thallapally obtained his PhD in 2003 from the University of Hyderabad working with Prof. Gautam R. Desiraju on crystal engineering and polymorphism. After graduation he moved to the Prof. Jerry L. Atwood research group at the University of Missouri-Columbia (UMC) as a postdoctoral research associate where he investigated gas storage and separation using porous organic and metal coordination solids. In 2006 he moved to Pacific Northwest National Laboratory (PNNL) as a Sr. Research Scientist. His research interests include the fundamental understanding of nucleation and crystal growth of nanostructured materials, gas separation, adsorption cooling, separation and immobilisation of radio nuclides (Kr, I Daryl Brown obtained his MBA in 1986 and has acquired a broad range of experience directing and performing analyses of advanced technology systems.
