CATALYTIC AND PHYSICO-CHEMICAL PROPERTIES OF CuO-Bi_2O_3 MIXED OXIDES BEFORE AND AFTER THEIR IRRADIATION

摘要

Some physico-chemical and catalytic properties of two-component CuO Bi_2O_3 catalysts containing various ratios of both components in the range 0-100 wt% of one component have been tested before and after γ- and electron-irradiation, using the decomposition of hydrogen peroxide as a test reaction. Irradiation led to modification of mutual influence of both components in the system accompanied by creation of radiolytically induced catalytic sites.
