a Electrochemical flow cells for the differential electrochemical mass spectrometry (DEMS) setup and the DEMS dual thin-layer electrolyte flow cell (MS: mass spectrometry). b DEMS signals for 32O2 (16O16O) and 34O2 (16O18O) from the reaction products for the 18O-labeled BCS-PBCC catalyst in H216O aqueous KOH electrolyte and the corresponding CV cycles. The mass spectrometry signals were baseline-subtracted. c, d Plots of the DEMS signals versus time for 32O2 (16O16O), 34O2 (16O18O), and 36O2 (18O18O) in the reaction products.
