The catalytic activity of Ni3Al foils for methane steam reforming was investigated by isochronal test from 873 to 1173 K, and the stability at 973 K for 20 h was also studied by isothermal test. Further, the effect of pretreatment, which was steam-oxidation then reduction at 873 K on the catalytic property, was also investigated. The results of catalytic reactions and the microstructure observations by SEM showed that the Ni3Al foils whether or not through the pretreatment all had certain activities and stabilities. The pretreatment significantly enhanced the catalytic activity of Ni3Al foils. Ni-enriched outer surface formed after the pretreatment was thought as the main reason of the enhancement. It was also considered that the Ni atoms moved from the matrix of Ni3Al foils to the outer surface during the reactions were attributed to the catalytic stabilities.
