제목 Electrochemistry of quaternary ammonium polybromide droplets
초록 In this presentation, electro-analyses of electrochemically generated quaternary ammonium polybromides (QBr2n+1) on Pt ultramicroelectrode (UME) are introduced. (1) we report the electrochemistry of Br− electro-oxidation in MEPBr2n+1 droplets during their collision on Pt UME through the current transient method, and reveal that MEPBr2n+1 also plays a vital role as an electrochemical reaction medium for Br− electro-oxidation in the Br−/Br2 redox system. (2) we present Br- electro-oxidation in QBr2n+1 strongly depends on Q+, and Br- transfer from aqueous to QBr2n+1 is the important preceding step for Br- electrolysis during the collision of QBr2n+1 droplets on Pt UME. (3) we found ions transfer from water to QBr2n+1 droplets was important for Br--electrolysis in QBr2n+1 droplets during their particle-impacts on Pt UME.
