Solvent co-deposition during oxygen reduction on Au in DMSO LiPF6

Rotating ring disk electrode (RRDE) and electrochemical quartz crystal microbalance (EQCM) have been employed for chronoamperometry of the oxygen reduction reaction (ORR) on gold electrodes in O2 saturated LiPF6/DMSO electrolyte. The Au ring electrode (ER = 3.0 V) detects a small fraction of soluble...
