The metal organic framework compounds as a new porous materials which self-assembled with inorganic vertices (metal ions or clusters) and organic struts can be used in carbon dioxide capture and separation due to their have advantage of the degree of orderliness, the high surface, diversity structures, tunable structures and modification porous. In this paper, the research progress of metal organic frameworks in application of carbon dioxide capture and separation in recent years are reviewed. Several methods for improving carbon dioxide capture and separation capability are systematically summarized. The methods mainly including design and synthesis MOFs with the high specific surface area, pore volume and suitable pore size, design and synthesis MOFs with the open unsaturated sites, design and synthesis flexible MOFs, design and synthesis MOFs modified with organic functional groups, post-synthesis modification of MOFs. The disadvantage of MOFs (including low effectively, high cost, low
