Abstract. Samples from NixCo3-xO4 system, with different dopant content, x, have been prepared by means of Pechini method. The materials are characterized by physical chemical methods, i.e. X-ray diffraction and infrared spectroscopy. The conductivity has been determined by impedance spectroscopy analysis. Electrochemical tests have been carried out to define the catalytic activity.
