The increase in exhaust of CO2 gas has created a undesirable change into atmosphere, which leads to global warming and unfavourable climatic change. Therefore capturing for CO2 gas has become a global anxiety. Coal-mine stations generate the majority of the world's electricity, Stakeholders environmentalists, and Researchers have paid close attention to CO2 capturing using combustion technology using a variety of technological alternatives such as membrane separation, adsorption, absorption, and chemical loop combustion in presence and absence of oxygen. Meso, Micro and porous adsorbents can be used to collect carbon from exhaust gases. Carbonaceous MOF and non-carbonaceous and mesoporous adsorbent for CO2 capturing under various pore size and surface area are discussed in this study. The mesoporous adsorbents and non-carbonaceous micro are also being studied in chemical loop combustion with in situ CO2 capture at elevated heat (>400 °C). The mechanics of adsorption, material properties, and synthesis techniques are all explored. Isosteric temperatures and characterization approaches are discussed. The prospects for improving the techno-economic feasibility of carbon capturing systems by combining them with CO2 to create industrial essential compounds such as ammonia and urea are investigated.
