摘要：
The catalytic behaviour of vacuum-deposited silver films (before and after bombardment with 4 keV Ar+ ions in doses of 10(17) cm-2) was examined. A heterogeneity of film surfaces with respect to the activation energy of the active centres for H2O2 decomposition was observed. The higher catalytic activity established for the bombarded films is attributed to changes in both the preferred orientation of the crystallites and the oxygen adsorptivity of silver films resulting from the bombardment.
