XPS Study of Poisoning Mechanism of O2 on LaNi4.7Al0.3 Oxygen

In this paper, LaNi4.7Al0.3 alloy samples were obtained via melting in middle frequency influence fire .In addition, The alloy pellets were milled for absorbing and desorbing Hydrogen ability study, The P-V-T measurement provided us with poisonous effect on the oxidation of LaNi4.7Al0.3.To understand the poisoning mechanism of O2 on LaNi4.7Al0.3, the X-ray photoelectron spectroscopy (XPS) was introduced to analyzed the process of poisoning of LaNi4.7Al0.3 alloy, Which revealed the changes of the valence of the elements of the alloy LaNi4.7Al0.3 poisoned by O2.
