Surface strontium enrichment on highly active perovskites for oxygen electrocatalysis in solid oxide fuel cells

Perovskite oxides have high catalytic activities for oxygen electrocatalysis competitive to platinum at elevated temperatures. However, little is known about the oxide surface chemistry that influences the activity near ambient oxygen partial pressures, which hampers the design of highly active cata...
