Effect of drying with supercritical carbon dioxide on enhancement and modification of polymeric catalysts' activity

Contributions of supercritical fluid technology for advancing decellularization and postprocessing of viable biological materials

“…Supercritical CO 2 drying was first applied in 1992 by Jarzebski, Andrzej B. et al 144 in raw polymeric catalysts. The technique is usually a solvent exchange process in which an organic solvent that is soluble in CO 2 , such as ethanol, methanol, or acetone is solubilized in supercritical carbon dioxide, while CO 2 fills the space occupied by the solvent and hence avoiding the collapse of the structure.…”
