- 論文の詳細を見る
In this study, the effect on crystallite size of oxidation temperature, oxidation time, and reduction temperature was investigated by the LaM5 method to clarify the factors controlling catalytic properties. When nickel was oxidized, the increase in surface area due to powdering was considerable. A model of the surface area increase was proposed based upon a shrinking-core model. An increase in the oxidation and reduction temperatures was accompanied by an increase in crystallite size.
