摘要：

Direct air carbon capture (DAC) is vital to achieving negative CO2 emissions, with physical adsorption offering a cost-effective and energy-efficient solution. an advanced zeolite modification technique is presented using cold plasma, which enhances the CO2 adsorption efficiency of NaX zeolite by 11.5% after just 60 min. This method utilizes the electric field to reorganize cation distribution and pore structure and significantly improve the adsorption capacity, efficiency, and selectivity. Compared to traditional methods, this technique is simpler and more effective, as demonstrated through first-principles calculations, thermodynamics, kinetics, and adsorption equilibrium studies.
