**3. Conclusion**

In this chapter, we highlight important aspect of some promising materials, like MOFs, POPs, nanoporous carbon and porous clays as CO2 adsorbents, which possess high BET surface area, tunable microporosity and facile surface engineering for enhancing interaction with CO2 . All such features are however exempted from conventional zeolites, alkali metal oxides, activated carbon, porous silica, therefore, demonstrating the significance of new porous materials in developing carbon capture techniques. Considering the growth of rapid industrialization and abrupt emission of CO2 in the atmosphere, an increasing concern to the social as well as marine lives, would be diminished through utilization of aforesaid functional materials to adsorb CO2 . In the abovementioned sections, we have thus tried to summarize the recent advancement made in the synthesis and broad prospect of MOFs, POPs, nanoporous clays and porous carbon as potential adsorbents for CO2 capture and storage. Nevertheless, in the near future, such promising materials would motivate to the researchers to extend this work towards low pressure CO2 adsorption, which may open a new route in the frontier area of carbon capture and sequestering study through the real world CO2 capture under ultra-dilute condition.
