Effect of gamma irradiation on gas-ionic liquid and water-ionic liquid interfacial stability

► The effect of gamma-irradiation of IL either in contact with water or with gas was studied by conductivity measurements and Raman spectroscopy. ► In the IL-water biphasic systems, γ-irradiation does not significantly induce chemical decomposition of the IL molecules into smaller products. ► Radiation increases the IL cation and anion interfacial transfer rates and accelerates micelle formation. ► This work is the first to observe radiation-induced IL-water phase mixing. ► A mechanism is proposed, showing that γ-radiation affects the potential gradient at the interface, increasing interfacial charge transfer.
