Sulfur Resistant Perovskite Electrocatalysts for High Temperature Applications

Owing to increasing demand for catalytic operations in clean and carbon negative energy systems, development of catalysts and electrocatalysts has been gaining importance and interest has been growing in mixed oxides (perovskites) that are known for their chemical and thermal stability. In the present work, some perovskite catalysts/electrocatalysts, mostly with structures ABO3 and AxA’(1-x)ByB’(1-y)O3 containing Co, Cr, La, Mo, Sr and V have been developed and studied in terms of electrical conductivity at increasing temperatures up to 1100 K. Among the samples, La0.9Sr0.1Cr0.5V0.5O3, LaSr0.5V0.5O3 and La0.9Sr0.1Cr0.75Co0.25O3 had relatively higher conductivity
