title: Aqueous emulsion containing fluorous cobalt species in supercritical CO2 for catalytic air oxidation of toluene.
abstract: An aqueous emulsion containing ionic Co2+ and Br- species stabilised by fluorous surfactant-like species in supercritical CO2-air mixture acts as a nano-reactor with excellent interfacial contacts of all necessary hydrophilic/hydrophobic species, which renders safe operation of catalytic aerial oxidation of toluene at high yields.
