摘要：

The interaction of nitric oxide with single-crystal surfaces of alumina at temperatures of 298, 473, and 673K, which had been covered by various amounts of iron, was studied using X-ray photoelectron spectroscopy. The iron was deposited onto Al//2O//3 in the Fe**0 state. At low coverages, iron was partially oxidized due to its interaction with Al//2O//3. Scanning auger mapping analysis showed that the iron was randomly distributed on the Al//2O//3 surface. The amount of adsorbed NO increased with increasing iron coverage. However, at very high iron coverages, there was a decrease in adsorption. This indicated that the aluminum ions may have activated the NO adsorption on the iron atoms.
