Abstract

Different citrate precursor powders of lanthanum chromite doped with copper LaCr1−xCuxO3 (0 ≤ x ≤ 0.4) have been synthesized by sol–gel method. After calcination, its structural and surface characteristics have been examined by X-ray diffraction to confirm the formation of the pure perovskite phase. Fourier transform infrared, differential thermal analysis and thermogravimetric analysis results indicate that the pure orthorhombic phase was obtained at temperature above 800 °C. The structure and morphology of the samples are characterized by SEM measurements indicating that the particles have nearly spherical shapes and are agglomerated. The study of electrochemical behavior shows that the electrode with large copper content has a better electrocatalytical activity.
