Abstract

Based on the concept of collective vibrations of ions in the bulk of metal systems, the frequency of vibrations of an oxygen molecule on the aluminum–cerium alloy surface has been evaluated. Numerical estimation of the physical adsorption isobar has been carried out in accordance with the Henry law using these data and the heats of oxygen adsorption on the surface of this alloy in amorphous and polycrystalline states obtained on the basis of optical experiment data. It has been shown that changes in the alloy’s electronic structure upon splitting of the conduction band for the amorphous state has a significant effect on the qualitative characteristics of the adsorption process.

多晶态和非晶态铝铈合金表面氧吸附过程的动力学

摘要

基于整个金属系统中离子的集体振动概念，评估了铝铈合金表面上氧分子的振动频率。使用这些数据，根据亨利定律对物理吸附等压线进行了数值估算，并根据光学实验数据获得了非晶态和多晶态下该合金表面的氧吸附热。已经表明，当非晶态的导带分裂时，合金的电子结构的变化对吸附过程的定性特性具有显着影响。
