The states of Ni, Mo, Ti and O in the catalysts were examined on a ThermoFischer ESCALAB 250Xi X-ray photoelectron spectrometer equipped with Al X-ray source (Al Kα, 1486.6 eV). All spectra were processed using the Shirley background correction, and calibrated with the C 1s component at 284.8 eV. The Gaussian–Lorentzian line shape was adopted to fit the spectra.
