Figure 3 | EOM mechanism analyses over NiO/Ni. (a) In-situ Raman spectroscopic analysis of the NiO/Ni catalyst and the local magnification of NiO/Ni Raman spectrum (b) at different potentials in 0.1 M NaOH aqueous electrolyte. The corresponding LSV profile is shown in the right panel and the potential of each spectrum is labeled between the spectra and the LSV curve vs. Ag/AgCl. (c) The valence band edge (Eedge) in UPS spectra of NiO/Ni catalysts before and after electrolysis. The inset shows the productivity of oxygenates at different applied currents. (d) MS spectrum for the CH3CH2OH product in 18O-containing electrolyte over NiO/Ni at 1 mA for 24 h and typical MS spectrum for CH3CH2OH. (e) The Ni 2p (e) and the O 1s (f) XPS spectra of NiO/Ni electrolysis at the applied currents of 1mA and 0.2 mA.
