Implementing Paris Climate Accord is inhibited by the high energy consumption of the state-of-the-art CO₂capture technologies due to the notoriously slow kinetics in CO₂desorption step of CO₂capture. To address the challenge, here we report that nanostructured TiO(OH)₂as a catalyst is capable of drastically increasing the rates of CO₂desorption from spent monoethanolamine (MEA) by over 4500%. This discovery makes CO₂capture successful at much lower temperatures, which not only dramatically reduces energy consumption but also amine losses and prevents emission of carcinogenic amine-decomposition byproducts. The catalytic effect of TiO(OH)₂is observed with Raman characterization. The stabilities of the catalyst and MEA are confirmed with 50 cyclic CO₂sorption and sorption. A possible mechanism is proposed for the TiO(OH)₂-catalyzed CO₂capture. TiO(OH)₂could be a key to the future success of Paris Climat e Accord.

Ionic liquids (ILs) have been used for carbon dioxide (CO₂) capture, however, which have never been used as catalysts to accelerate CO₂capture. The record is broken by a uniquely designed IL, [EMmim][NTf₂]. The IL can universally catalyze both CO₂sorption and desorption of all the chemisorption‐based technologies. As demonstrated in monoethanolamine (MEA) based CO₂capture, even with the addition of only 2000 ppm IL catalyst, the rate of CO₂desorption—the key to reducing the overall CO₂capture energy consumption or breaking the bottleneck of the state‐of‐the‐art technologies and Paris Agreement implementation—can be increased by 791% at 85 °C, which makes use of low‐temperature waste heat and avoids secondary pollution during CO₂capture feasible. Furthermore, the catalytic CO₂capture mechanism is experimentally and theoretically revealed.
