Zeeshan & Gurkan (2025): Sorbent Regeneration via Radiofrequency-Assisted Dielectric Heating for Direct Air Capture of CO2

Muhammad Zeeshan and Burcu Gurkan IN: ACS Applied Engineering Materials, https://doi.org/10.1021/acsaenm.5c00202

The authors report an unconventional approach to desorb captured CO₂ from a porous sorbent using radiofrequency (RF) irradiation for dielectric heating and targeted energy transfer, thus enabling modularity and promoting renewable energy input. Regeneration of composites of functional ionic liquid and metal–organic framework with high CO₂ capacity and enhanced transport is demonstrated under conditions relevant to DAC.
