本文用XPS(X射线光电子能谱)研究了碱活化把、把银合金两种细管表面及其阴极电解透氢后的各种样品的表面。结果表明,活化表面为一层牢固的炭黑色水合氧化钯((PdOH)_2O);其阴极电解透氢后仍有活性的表面为一层电子不足化合物(〔PdH〕),而失活表面为一层钯黑,并且这三种钯银合金的表面上均无银的信息。
In this paper, XPS (X-ray photoelectron spectroscopy) was used to study the surface of various samples after alkaline activation and electrolysis. The results show that the activated surface is a solid layer of carbon black hydrous palladium oxide (PdOH) _2O). The active surface of the active surface after the cathodic electrolysis is an electron-deficient compound (PdH) A layer of palladium black, and no silver on the surface of all three palladium silver alloys.
