A method for capturing CO.sub.2 from a gas stream using a metal organic framework (MOF) based physisorbent CO.sub.2 concentrator is provided. In the method, MOF material is pretreated, a gas stream is then introduced into the CO.sub.2 concentrator which comprises the pretreated MOF material. CO.sub.2 from the gas stream is captured with the CO.sub.2 concentrator to generate a CO.sub.2-free stream, which is discharged the from the CO.sub.2 concentrator into the atmosphere. Introduction of the gas stream into the CO.sub.2 concentrator is stopped when the pretreated MOF material becomes saturated with CO.sub.2. The CO.sub.2 concentrator with the saturated MOF material is then regenerated by introducing hot air, hot nitrogen, vacuum, or a combination thereof into the CO.sub.2 concentrator thereby generating a CO.sub.2-rich stream. The CO.sub.2-rich stream is diverted for purification and the regenerated CO.sub.2 concentrator is recycled for future capture of CO.sub.2.
