To clarify the potential of Ni surfaces as an alternative catalyst of Pt for exhaust gases of automobiles, the oxidation and reduction reaction kinetics on Ni(111) surfaces were investigated by X-ray photoelectron spectroscopy using synchrotron radiation (hv = 1100 eV) at BL23SU, SPring-8. By annealing at 700℃ under H₂ atmosphere at P_H2 = 9×10^-4 Pa for 600 s, there were no traces of carbon, oxygen, sulfur, and chlorine contaminants within the detection limit.
