carbon dioxide plays the role of a reactant,
CO 2 -rich conditions such as supercritical
conditions are suitable for improving product
yields.

As mentioned above, conventional supercritical
fluids like supercritical carbon dioxide are the
low dielectric constant of the fluid. Hence,
many supporting electrolytes are usually hard
to dissolve in the fluid. A polar organic solvent
should therefore be added to the fluid to
produce a suitable electrolytic solution.
However, the inclusion of a co-solvent limits
the accessible potential range and introduces
complications. The use of supercritical
