Electrochemistry of soluble UO22+ from the direct dissolution of UO2CO3 in acidic ionic liquid containing water

► The direct dissolution of uranyl carbonate into wet ionic liquid containing HTFSI was achieved. ► The soluble species from the dissolution UO2CO3 in water and IL containing HTFSI was probed using UV/vis spectroscopy. ► Electrochemical deposition of UO2 from IL was achieved at an Au electrode in the presence of water. ► The deposition of UO2 at Au was confirmed using SEM/EDX analyses.
