Water-in-Supercritical CO sub(2) Microemulsion Stabilized by a Metal Complex

Herein we propose for the first time the utilization of a metal complex for forming water-in-supercritical CO sub(2) (scCO sub(2)) microemulsions. The water solubility in the metal-complex-stabilized microemulsion is significantly improved compared with the conventional water-in-scCO sub(2) microemu...

Description
Summary:Herein we propose for the first time the utilization of a metal complex for forming water-in-supercritical CO sub(2) (scCO sub(2)) microemulsions. The water solubility in the metal-complex-stabilized microemulsion is significantly improved compared with the conventional water-in-scCO sub(2) microemulsions stabilized by hydrocarbons. Such a microemulsion provides a promising route for the insitu CO sub(2) reduction catalyzed by a metal complex at the water/scCO sub(2) interface.Original Abstract: An der Grenze: Durch Verwendung eines Metallkomplexes wurden Mikroemulsionen von Wasser in ueberkritischem (sc) CO sub(2) erhalten, an deren Wasser-scCO sub(2)-Grenzflaechen die In-situ-Reduktion von CO sub(2) zu Ameisensaeure gelingt. Der Prozess ist hoch effizient, verfuegt ueber eine einstellbare Aktivitaet und ermoglicht die leichte Abtrennung von Produkt und Katalysator.
