A Novel Phase-Changing Nonaqueous Solution for CO2 Capture with High Capacity, Thermostability, and Regeneration Efficiency

“…Several types of organic solvents can be used in the solutions, which include ethylene glycol, diethylene glycol, and triethylene glycol. Thereinto, poly­(ethylene glycol) (PEG) is an environmentally benign solvent with some appealing properties similar to ionic liquids (ILs), such as low toxicities, good chemical and thermal stability, and negligible vapor pressure. − Moreover, PEGs are inexpensive and have lower viscosity than ILs . Some studies indicate that CO 2 also exhibits high solubility in PEGs due to the quadrupole interaction of CO 2 with polar ether oxygens. − Hence, some researchers use PEGs as a cosolvent for ILs to decrease the viscosity of ILs after CO 2 absorption.…”

A depth-suitable and water-stable trap for CO2 capture

“…On the contrary, some carboxylates can absorb CO 2 under certain conditions. [20][21][22][23][24][25][26] So, there must be an intermediate in this reaction, which is relatively stable under certain conditions. Bicarbonate is a reasonable explanation, and Yasaka et al considered that bicarbonate is stabilized by a hydrogen bond with a carboxylic acid.…”
