摘要

采用原子发射光谱法(AES)和原子能谱法(ESCA)研究了常温下氧在多晶锆上的化学吸附。结果表明，高温退火大大降低了锆的化学吸收氧的能力，但氩离子轰击可以恢复其活性。这表明化学吸附可能是位点特异性的，这些位点的浓度可以通过不同的样品预处理来控制。

An investigation of the interaction of polycrystalline zirconium with O2, N2, CO and N2O

The chemisorption of oxygen at room temperature on polycrystalline zirconium has been studied using AES and ESCA as a function of sample pretreatment. It is shown that annealing at high temperature greatly reduces the ability of zirconium to chemisorb oxygen but that its activity can be restored by argon-ion bombardment. This suggests that chemisorption may be site specific and that the concentration of these sites can be manipulated by varying sample pretreatment.
