Physicochemical study of electrochemically reduced manganese cobaltite corresponding to mn/Co = 0.5 ratio.

The structural modification of spinel phase by cathodic electroreduction is shown. For the manganese-cobalt oxide prepared at high temperature and electrochemically reduced at 2.5 mA cm-2 In acid media it was possible to obtain the global formulae and the probable ionic distribution between the tetrahedral and octahedral sites of the spinel. The obtained results lead us to increase the knowledge of reduced oxide interesting for the electrochemical cathode In energy convertion cells and/or electrosynthesis cells
