The challenge in deploying energy-efficient DAC lies in effective sorbent materials. In this research, the authors comprehensively investigated the DAC behavior of LTA zeolites exchanged with different metal cations (Na+, K+, Mg2+, Ca2+, Mn2+, Co2+, Ni2+, Cu2+, Zn2+, Y3+, La3+, Ce3+, Eu3+, Tb3+, and Yb3+) by both static single-component gas adsorption and dynamic mixture gas adsorptive separation tests.
