🚨NEW PAPER 🚨
"The energy-intensive nature of CO2 absorption-desorption processes has restricted deployment of #DAC operations. So, catalytic solvent regeneration is a valid solution to tackle this case by accelerating CO2 desorption at lower regeneration temperatures."

"The assembly of citrate groups on the surface of MCSs enables consistent spherical growth morphology, reduces agglomeration & enhances H2O dispersibility. The functionalization-assisted synthesis produces uniform hydrophilic nanospheres of 100–600nm range."

"This work also demonstrates that the prepared MCSs can be further functionalized with strong Brønsted acid sites, providing high proton donation ability."

Furthermore, "the materials can be effectively used in a wide range of amino acid solutions to substantially accelerate CO2 #desorption (25.6% for potassium glycinate and 41.1% for potassium lysinate) in the #DirectAirCapture process."

"Considering the facile synthesis of MCS-SO3H and their superior catalytic efficiency, these findings are expected to pave a new path for energy-efficient #DirectAirCapture."
