CuO is immobilized on electrically conductive carbon particles and its electrocatalytic properties in a cationic surfactant solution are investigated. The properties are measured with a sandwich type two-electrode cell and a common three-electrode bulk cell. Measurements with the sandwich type cell show, that the immobilization on conductive particles promotes the anodic oxidation of Cu(II) to Cu(III). The properties are also investigated with the bulk cell using organic sulfur- and chloro-compounds as substrates. The immobilized CuO shows higher catalytic activity for the indirect electrolysis ortho compounds.
