Abstract: CO2 is one of the most important greenhouse gases and its removal from flue gas and natural gas has become increasingly important. We report the synthesis, characterization, and CO2 adsorption properties of two similar metal organic frameworks; Co and Ni based MOF-74. The BET specific surface areas of MOF-74(Co) and MOF-74(Ni) MOFs were 1,406 and 1,418 mg, respectively with the identi...
