采用光电子能谱（ＸＰＳ）研究了氨氧化装置中使用的高Ｐｄ合金的表面状态，并用不同方法制备４种Ｐｄ氧化物以便比较。测定Ｐｄ氧化物的Ｐｄ３ｄ＿（５／２）电子结合能（ＢＥ）值为３３７．０±０．２ｅＶ。Ｘ射线结构（ＸＲＤ）分析确定这些氧化物为ＰｄＯ。
The surface states of high Pd alloys used in the ammoxidation plant were studied by photoelectron spectroscopy (XPS) and four different Pd oxides were prepared for comparison. The Pd3d_ (5/2) electron binding energy (BE) value of Pd oxide was 337.0 ± 0.2eV. X-ray structure (XRD) analysis confirmed that these oxides were PdO.
