【 摘 要 】

References(9)Cited-By(6)It is known that the catalytic activity of LaNi5 increases during CO hydrogenation due to a structure change into Ni/La2O3 by oxygen. Oxidation treatment is therefore thought to be useful in controlling nickel dispersion on the surface area. However, few studies of the relation between oxidation of LaNi5 and nickel dispersion have been made. Consequently, in this study the effects of oxidation on nickel dispersion under various oxidation temperatures and uptakes of oxygen per total weight were examined.
