Abstract
EFFECTS of nuclear radiation on heterogeneous catalysts has been the subject of various investigations in the past few years1,2. These investigations have shown that significant changes due to irradiation are produced in the catalytic behaviour of some oxides and metals. The phenomenon is due to the fact that catalytic activity is strongly dependent on the structure of solids and this structure may be modified on irradiation. Nuclear radiations may create in semiconductors new energetic levels, which change the position of the Fermi-level in the solid. This leads to changes in various structural sensitive properties, for example, the activation energy of the reaction catalysed by the surface of the solid3.
