High current densities during CO2 reduction in gas diffusion electrode (GDE) flow cells are incompatible with present online product-profiling methods. With the adaptation of proton-transfer reaction time-of-flight mass spectrometry, operando mechanistic information on C1–C4 product formation at copper-based GDEs is now accessible.
