概要
- 論文の詳細を見る
The isoelectric point and the nonstoichiometric composition of the surface layer were measured for manganese oxide samples treated <I>in vacuo</I> or in air at elevated temperatures. It was found that the surface composition of most samples tested was oxygen-deficient with reference to the bulk composition, and that the IEP was determined by the bulk structure rather than the surface composition. This was ascribed to the fact that the surface is heterogeneous and the dissolution of the solid will take place preferentially at surfaces which involve defect structures or Mn(II) ions.
