摘要：

In situ X-ray diffraction measurements of small supported silver particles are performed under defined atmospheres in the temperature range of 298-723 K. We find a reversible change in lattice parameter of silver particles against the atmosphere exchange between 5%H2/He and 1%O2/He. The data indicate that the oxygen-induced lattice dilatation observed here is due to the reduction in surface stress which is caused by not only the static effects of oxygen adsorption but also the induced change in the structure of silver particles. © 1990.
