Lanthanum strontium cobaltite, LaxSr1-xCoO3, (LSCO) is among the perovskites observed to have high potential as a bifunctional catalyst for ORR and OER. Silver metal, Ag, a low-cost and abundant, but also considered a noble metal, is regarded as a good replacement for expensive Pt electrocatalysts because of its high catalytic activity. The excellent ORR catalytic activity of Ag catalyst and the bifunctional catalytic activity of LSCO can be a promising hybrid catalyst that can be used for ORR and OER. Ag nanoparticles are chemically deposited on LSCO powder. This study determines the electrocatalytic performance of both Ag metal and LSCP catalyst in an alkaline solution. |
