W.K. Shi, Y. Ji, X.J. Zhang, M.X. Fang, T. Wang, L. Jiang IN: Carbon Capture Science & Technology 7, 100114, https://doi.org/10.1016/j.ccst.2023.100114
Despite being introduced in 1999, large-scale DAC application remains challenging. Nevertheless, various research efforts regarding material development, process construction, and application continue to expand. The research focuses on advanced sorbents such as quaternary ammonium and chemical sorbents for moisture swing adsorption (MSA) and thermal-driven adsorption cycles. The working mechanism of MSA, the interfacial and structural characteristics of sorbents, and their effects on sorption performance are further analyzed.
