The technology of carbon capture

utilization and storage(CCUS) is one of the important measures to alleviate global climate change. Nanoparticles with good surface and volume effect are favored because of their ability to enhance the mass transfer performance of CO_2 capture. They can increase the mass transfer coefficient of CO_2 absorption in amine solutions and reduce the energy needed for solvent regeneration

which is expected to further improve the CO_2 capture efficiency and reduce energy consumption. In this paper

three mechanisms of nanoparticles enhanced CO_2 absorption are discussed: the mechanism for inhibition of bubble coalescence

the mechanism for shuttle effect and the mechanism for mixing of the gas-liquid boundary layer. The latest research progress at home and abroad in recent years is summarized

and the main influencing factors in the process of CO_2 absorption enhanced by nanoparticles are discussed. It points out that the enhancement of CO_2 absorption process by nanoparticles is the result of the joint action of multiple factors. Moreover

the future direction of this technology is prospected.
