    Fig. 9B shows the O 1s XPS spectra of the pure NiO and NiCeOx catalysts prepared using different methods. All the catalysts displayed two peaks at 529 and 531 eV, which were assigned to lattice oxygen (O2−) and surface oxygen (O−), respectively [36,52,53]. The relative intensities of these two peaks for NiO and NiCeOx catalysts are ordered as follows: NiCeOx-4 (0.53) > NiCeOx-CP (0.48) > NiCeOx-CA (0.44) > NiCeOx-Mix (0.42) > NiO (0.36).

    It might be because higher valence Zr4+ is easier to induce O2− than Ni2+, so the electron density around O2− decreases and subsequently results in the increase of the O1s B.E. In the Ni2p3/2 spectra, all the samples exhibited two resolvable peaks at B.E. of around 853.4 and 855.3 eV, with a shakeup satellite at ∼860.5 eV, which are assigned to Ni2+ and Ni3+ species [34–36]. The Ni2p3/2 binding energy was seen shifting to higher values with increasing Zr content, from 853.9 eV (5%) to 855.4 eV (75%).
