Gamma-irradiation effect on the catalytic behavior of binary oxide catalysts.

概要

Decomposition of hydrogen peroxide in aqueous solution was used for testing the effect of gamma radiation on the catalytic activity of CoxFe3−xO4, with O≤x≤3.0. The activity variation was interpreted in terms of the catalysts electronic structure. The presence of Co2+ on octahedral sites is superior to Fe2+ in the catalytic process. However, γ-irradiation can produce a considerable effect on the catalytic activity due to its influence on the active site concentration and cation distribution.
