“Moreover, five adsorption/desorption cycles were run to investigate its reproducibility, as seen in Fig. 12. It was found that the CO₂ adsorption capacity of 50EAE-10TEPA/MCM-41 dropped by 9.4% after five repeated adsorption–desorption cycles, which indicated the incomplete regeneration at 100°C.”
