Electronic interaction in oxide copper-cerium catalysts according to exoemission data

The electronic properties of the oxide copper-cerium catalysts with different copper content are studied through the exoemission methods. It is shown, that the introduction of the copper increases the CeO2 emission activity and the number of the electrons, emitted from the catalysts surface, as compared to the surface of the CeO2 and CuO initial oxides. It is concluded, that the event of synergism in the exoemission from the studied systems surface is conditioned through the electronic interactions, including the electronic transitions on the cerium oxide - copper oxide boundary
