Among thousands of known metal-organic frameworks (MOFs), the University of Oslo's MOF (UiO-66) exhibits unique structure topology, chemical and thermal stability, and intriguing tunable properties, that have gained incredible research interest. This paper summarizes the structural advancement of UiO-66 and its role in CO2 capture, separation, and transformation into chemicals. The first part of the review summarizes the fast-growing literature related to the CO2 capture reported by UiO-66 during the past ten years. The second part provides an overview of various advancements in UiO-66 membranes in CO2 purification. The third part describes the role of UiO-66 and its composites as catalysts for CO2 conversion into useful products. Despite many achievements, significant challenges associated with UiO-66 are addressed, and future perspectives are comprehensively presented to forecast how UiO-66 might be used further for CO2 management.
