| dc.description.abstractEn | The present work is devoted to the investigation of temperature programmed oxygen desorption - sorption (TPD) processes performed on SOFC innovative cathode materials with Pr2-xLaxNiO4+δ composition. The experiments were performed using the coulometric titration technique involving an OXYLYT™ device, over the temperature cycle 20 – 900 – 20 °C. The considered parameters were the time and temperature dependences of both the titration current and the oxygen over-stoichiometry. TPD spectra of Pr2-xLaxNiO4+δ (x ≠ 0) exhibited two sharp peaks (maxima) of titration current with excellent resolution at p(O2) = 50 Pa, induced by removal of oxygen from different sites of the crystal lattice. TPD spectrum of Pr2NiO4+δ recorded under the same conditions drastically differs from the spectra of Pr2-xLaxNiO4+δ as four sharp maxima of titration current are detected. The TPD spectra of Pr2-xLaxNiO4+δ then strongly depend on the nature of the rare-earth (La or Pr) in link with the oxygen over-stoichiometry amount. | |
