Figure 15. (A) In situ Raman spectra of NiSe_x/Ni NRAs at a constant potential of 1.35 V (vs. RHE) for 60 min during GOR and in situATR-FTIR spectra of NiSe_x/Ni NRAs for GOR collected at different potentials from open circuit potential (OCP) to 1.7 V (vs. RHE); (B) The calculated Gibbs free energy profiles of GOR on NiSe_x, NiS_x, NiO_x, and NiOOH^[180].

NRAs: Nanorod arrays; RHE: reversible hydrogen electrode; GOR: glycerol oxidation reaction; ATR: attenuated total reflection; FTIR fourier-transform infrared.
