Abstract Although Direct Air Capture (DAC) of CO 2 is a potential technology for climate change mitigation, the cost, scalability, and efficiency of existing materials and techniques are severely limited. MXenes, a type of two‐dimensional materials, have drawn interest due to their remarkable conductivity, enormous surface area, and adjustable chemistry, however, their potential for DAC has not yet been thoroughly investigated. Recent developments in MXene synthesis and functionalization are comprehensively reviewed, with an emphasis on how these characteristics might be used to enhance improve CO 2 adsorption and capture efficiency. In addition, the difficulties of stability, scalability, and economic feasibility for real‐world applications are evaluated. Our findings demonstrate the great potential of MXenes for DAC and offer fresh perspectives on how their special qualities might overcome current constraints. This study presents a new viewpoint on MXenes as a feasible CO 2 capture option, indicating new avenues for future research and development, even though further optimization is required.
