Efficient Solvent-Free Mechanochemical Synthesis of CALF-20 for Carbon Dioxide Capture

Abstract

A solvent-free mechanochemical synthesis of CALF-20 is proposed, offering a rapid and cost-effective route by eliminating the solvent used and the purification process. With a record space-time yield of up to 88,000 kg m^-3 d^-1, the mechano-synthesized CALF-20 exhibits a high CO₂ adsorption capacity, highlighting its potential for point-of-use carbon capture.
