To control the rising level of atmospheric carbon dioxide is a major issue and the challenge due to rapid population, industrialization and growing demand for energy. To meet the current demand of energy, 80 % of energy is produced by combustion of fossil fuels. Various methods and technologies have been developed for carbon capture, storage and reducing the harmful emission of CO2, but still it is a critical issue for the development of energy efficient CO2 separation. Although membrane based separation has been considered as capable technology, apart from established materials and techniques, the investigation of advanced polymers, filler’s with high performance and low cost, capable at severe conditions are vital and significant. The MOF’s and ZIF’s are an emerging class of nanoporous crystalline materials offers an exciting enormous prospect as filler particles in polymeric matrices. The objective of this review was to overview the different types of MOF and ZIF materials used as a filler, selection criteria, current status and development, parameters of separation, scalable fabrication at lower cost and enhance selectivity characteristics with those of inorganic materials. The most emphasis was towards CO2 /N2 separation in view of direct significance to the post combustion of fossil fuels to the gas separation. Also, the purpose of the study was to investigate and assess the future prospects and challenges of post combustion separation to achieve high selectivity and permeability at low concentration, low pressure and large volume of CO2 in presence of other contaminants.
