Despite numerous efforts to decarbonize the energy sector, the rapid increase in CO₂ global emissions continues. Thus, the role of carbon capture and utilization in attaining net zero emissions remains indispensable. This presentation aims to summarize emerging sorbents and technologies for CO₂ capture. Among sorbents available for CO₂ capture, eutectic mixture (EM)-promoted MgO-based sorbents are focused on due to their high sorption capacities. In-situ TEM studies show that EM-MgO undergoes rearrangement and EM migration after multiple uses, resulting in poor cyclability and reusability. Several strategies such as the use of stabilizers, supports, and employing a core-shell morphology were thus employed to achieve stable cyclic performances. Finally, electric field-assisted CO₂ capture was found to increase sorption performance while decreasing temperature and energy requirements.
