Abstract
Barium cerate BaCeO3 is obtained by a coprecipitation method. The crystallized samples are characterized by X-ray diffraction and electron microscopy. The structural and thermodynamic analyses revealed several transitions as a function of temperature according to the phase transformation. The electrical properties are studied using electrical impedance spectroscopy as a function of temperature. The Nyquist representations are semi-circles, characteristic of electron and ionic conduction. A series of electrical transitions are observed, which are in good agreement with structural transitions. The catalytic properties of these powdered materials in presence of air and 2500 ppm of carbon monoxide gas flows are studied by Fourier Transform Infrared spectroscopy (FTIR). The catalytic activity given rise to the total oxidation reaction and has been determined from the CO2 FTIR absorption band intensities. This activity reaches the complete transformation at 400°. The conversion rate of CO into CO2 is analyzed as a function of temperature and reaction time.
