title = "Rotating disk electrode-online electrochemical mass spectrometry for oxygen reduction reaction on pt electrode surfaces",
abstract = "Potential-dependent molecular behavior of dissolved O2 in the vicinity of a polycrystalline Pt electrode surface was studied in O2-saturated 0.1 M HCIO4 solution using a newly developed online electrochemical mass spectrometry (OLEMS) with rotating disk electrode (RDE) method (RDE-OLEMS). A gas sampling tip was positioned at-50 urn from the electrode surface; O2 concentration in the vicinity of the Pt electrode at open circuit potential (~0.8 V vs. RHE) depended on the disk rotation rates, and linear sweep voltammetry (LSV) of the Pt electrode showed diffusion-limiting currents in the RDE-OLEMS layout. Furthermore, simultaneously recorded RDE-OLEMS data for the potential-dependent O2 concentration were consistent with the LSV data recorded for a negative-going sweep. We have successfully applied the newly developed RDE-OLEMS method and it is effective for in-situ analysis of gaseous electrochemical reaction products and dissolved molecules in the vicinity of the electrode under electrochemical conditions.",
