Summary: In order to achieve a carbon-neutral world, it is necessary to remove the excess CO2 that has already been released into the atmosphere. Technological advancements have allowed for the development of CO2 capture methods from wet flue gas and ambient air, but their widespread implementation is still limited. Recent improvements in material assembly and surface chemistry have led to the production of water-stable and encapsulated metal-organic frameworks (MOFs) for CO2 capture. This article discusses the progress, insights, and future directions of these MOFs, specifically in the context of Direct Air Capture of CO2 and CO2 capture from wet flue gas.

Summary: Post-combustion carbon capture is an efficient way to mitigate CO2 emissions. However, traditional physical adsorbents face challenges in the presence of moisture. In this study, we synthesized polypyrrole adsorbent using Fenton's reagent and demonstrated its high adsorption capacity for CO2 in moist conditions. This green and facilely synthesized adsorbent has great potential for capturing carbon in high humidity flue gases.

Summary: The photoelectrochemical reduction of CO2 is a sustainable method for producing chemicals and fuels using sunlight as the energy source. This study investigates the effect of flue gas impurities and concentrations on the performance of photoelectrochemical CO2 reduction. It is found that NOx, SOx impurities, and low CO2 concentrations are compatible with the process, while the presence of O-2 impurity reduces the CO2 conversion efficiency, but this effect is reversible.
