Srivastava, Ashutosh published the artcileDeep eutectic solvents based on imidazolium cation and probing redox speciation of uranium oxides by electrochemical and theoretical simulation, Recommanded Product: 2,2′-Oxydiacetic acid, the main research area is imidazolium deep eutectic solvent electrochem thermogravimetric mol dynamics.
Two new deep eutectic solvents, different from hitherto known and based on common choline chloride, were prepared 1-methyl-3-decylimidazolium bromide mixed with hydrogen bond donors, malonic acid and diglycolic acid to form DES. Dissolution of uranium oxides (UO3 and UO2) was explored in both of them and characterization of the resultant solutions was carried out by IR, TGA and UV-Vis spectroscopy. Redox speciation of dissolved uranium oxides was probed in these redox-active DES through cyclic voltammetry, differential pulse voltammetry and in situ spectroelectrochem. measurements. Interestingly, the formation of uranium oxo species was observed through the dissolution of UO3 in both the DES. The electrochem. characteristics via redox thermodn. (peak potential and formal redox potential), transport property (diffusion coeffecient D0), heterogeneous electron transfer kinetic parameters (αn and k0) and mechanistic electron transfer of the dissolved uranium species in two DES were investigated. The speciation of uranium was decoded through the electronic absorption spectra of uranium in its lower oxidation states [U(V) and U(IV)] acquired through in situ spectroelectrochem. electrolysis with varying cathodic potentials. Studies were also carried out using mol. dynamics (MD) and d. functional theory (DFT) simulations to authenticate the electrochem. outcomes and to acquire the binding energy, optimized structure and MO diagram of dissolved uranium species. Further, the MD simulation sheds light on the probable equatorial coordinating atoms of dissolved uranium species. This is the first report, to the best of our knowledge, on imidazolium-based DES and actinide ions.
