Compositional effect on oxygen reduction reaction in Pr excess double perovskite Pr1+xBa1-xCo2O6-δ cathode materials

Influence of the crystalline phase on the electrocatalytic behaviour of Sm2−xSrxNiO4−δ (x = 0.4 to 1.0) Ruddlesden–Popper-based systems: a comparative study of bulk and thin electrocatalysts

“…28 Further, perovskites are also known to show the OER with a four-electron transfer. 29 CaMnO 2.5 has shown higher OERs than those of CaMnO 3 with the creation of molecular oxygen vacancies and high spin level configuration. 30 The A-site deficiency in LaFeO 3 significantly increased ORR and OER electrocatalytic activities.…”

“…An extensive literature survey reveals that compositional variation on the kinetics of the OER of Ruddlesden-Popper layered structured oxides is least investigated and Sm 2Àx Sr x NiO 4Àd is least studied for their catalytic mechanisms at the triple-phase boundary. [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] In order to understand the insight mechanism of electrocatalytic behaviours with phase and dimension, we have studied the compositional effect along with the studies in a thin film form. For this, we synthesized Sm 2Àx Sr x NiO 4Àd (x = 0.2, 0.4, 0.6, 0.8 and 1.0) via conventional solid-state reaction routes to form two structures, namely, tetragonal and orthorhombic with the change in oxygen stoichiometry.…”

Recent Development in Reversible Solid Oxide Fuel Cells: Theory, Integration and Prospective

“…The results indicate that Mo doping can be effectively employed for the cathode material of intermediate-temperature SOFCs. Bangwal et al [91] studied the effect of the Pr/Ba doping ratio on the properties of electrode materials. The single-and double-doped YBaCoCuO 5 + δ , YBaCoFeO 5 + δ , and YBaCo 2/3 Fe 2/ 3 Cu 2/3 O 5 + δ were comparatively studied to assess the influences of doping strategy on stability, thermal and chemical compatibilities by Liu et al [92] .…”
