Abstract

Herein we propose for the first time the utilization of a metal complex for forming water-in-supercritical CO₂ (scCO₂ ) microemulsions. The water solubility in the metal-complex-stabilized microemulsion is significantly improved compared with the conventional water-in-scCO₂ microemulsions stabilized by hydrocarbons. Such a microemulsion provides a promising route for the in situ CO₂ reduction catalyzed by a metal complex at the water/scCO₂ interface.

Keywords: CO2 reduction; iron complexes; microemulsions; photocatalysis; supercritical CO2.
