Synergistic effect of ionic liquid (IL) cation and anion inhibits negative difference effect on Mg in water - IL mixtures
Source abstract
Abstract
Strong Negative Difference Effect (NDE) is present on Mg alloys in [mPEG n MPyr]ClO 4 -H 2 O and [BMPyr]AcO-H 2 O but not in [mPEG n MPyr]AcO-H 2 O mixtures. The role of [mPEG n MPyr] + and its synergy with AcO - in water-ionic liquids mixtures were characterized combining surface analysis by ToF-SIMS, surface and solution analysis by vibration spectroscopies and molecular dynamics simulations . The NDE was explained by the “free” water phase formation when Mg 2+ -ions expel water initially H-bonded with AcO - . Oxygen atoms of [mPEG n MPyr] + can bond the released water, inhibiting the NDE. Water transport can be reduced by a condensed film, formed by [mPEG n MPyr] + and AcO - coordinated with Mg 2+ and Al 3+ .
