摘要: Abstract Some physico-chemical and catalytic properties of NiO–ThO 2 catalysts containing various amounts components in the range 0–100 wt% one component have been studied before after 1 MGy gamma or 3 accelerated electron irradiation air water using hydrogen peroxide decomposition as a test reaction. The γ -irradiation pure NiO led to significant changes surface oxidative ability well activity oxide. Dramatic (and partially also samples an excess NiO) were caused by reduction with hydrogen.
