In comparison with the pre-combustion, and oxy-fuel combustion, post-combustion for capturing and or conversion of carbon dioxide is growing attention because it is most feasible as it just needs retrofitting of the existing power plants. In fact, CO2 capture via post combustion using MOFs is a promising and sustainable emerging technology because of high BET surface area of MOFs, low operating cost, easy regeneration of the adsorbate, and little conventional process modification (less capital cost). CO2 control resulting from conventional fossil fuel burning which is the main contributor to the global warming. But still a cost-effective continuous process for CO2 capturing and conversion, needs further optimization to be implanted on the commercial scale for continuous large-scale operation. The current study briefly discusses the recent advance in synthesis methods, metal-ion/organic linkers, structure modifiers or fillers, and adsorption isotherms for ZIF-300 and ZIF-302. Finally, the comparison of the fitting parameters (equilibrium adsorption constant, order of adsorption, and enthalpy of adsorption) with the already published literature is highlighted.
