Abstract
The effect of60Co 
-radiation on La2CuO4 solid catalyst prepared by the ceramic method has been studied. Gamma irradiation of La2CuO4 samples has been found to increase the Cu+ content, electrical conductivities and decrease the magnetic susceptibilities of the catalyst. The results have been interpreted on the basis of the crystal field model of the structure of La2CuO4.
Abstract
The catalytic activity of La2CuO4 for the decomposition of H2O2 was studied in detail. La2CuO4 was prepared by the ceramic method in four different ways. Gamma irradiation of the La2CuO4 samples increased their catalytic activity irrespective of the method of preparation. The enhanced catalytic activity is attributed to irradiation generated Cu+ centres on the surface of the catalyst.
