Coal occupies a considerable proportion in global energy and will be one of the world's most important primary energy for a long time.However,the hazardous and pollutant gas generated in the process of coal mining and usage not only posed a threat to personal safety but also been contrary to the will of sustainable development strategy.As a result,the efficient use of coal has become an important and urgent problem to be solved.(MOFs) is a newly developed organic-inorganic hybrid material with certain pore size and surface area.The special structure of MOFs is decisive to its great application potential in gas separation and storage.Based on the structural charateristics of MOFs,the progress of MOFs in the adsorption and separation for CH4,CO2 was reviewed.
