Abstract

Ultraviolet photoelectron and thermal-desorption spectroscopy data showed that water molecules dissociate under ultrahigh vacuum on the surface of a single-layer alumina film formed on Mo (110) and maintained at a low temperature, and they are desorbed during subsequent thermally stimulated recombination as hydrogen, water, and oxygen. Several recombination channels of adsorbed particles are due to the complete decomposition of water molecules and the metastable single-layer oxide film incompletely formed from Al^(3 – x)+–O^{(2 – y)–} interionic bonds and its specific interaction with H, O, and OH particles.

水分子与Al 2 – x O 3 – y单层膜之间的相互作用

摘要

紫外光电子和热解吸光谱数据表明，水分子在超高真空下在Mo（110）上形成并保持在低温下的单层氧化铝膜表面上解离，并在随后的热刺激重组过程中被解吸为氢，水和氧气。吸附颗粒的几个重组通道是由于水分子的完全分解以及由Al ^{（3-  x）+} -O ^{（2-  y）-}离子键不完全形成的亚稳单层氧化膜及其与H的特定相互作用所致， O和OH颗粒。
