英文摘要The oxygen evolution reaction (oer) is a sluggish electrocatalytic reaction in solid oxide electrolysis cells (soecs) at high temperatures (600-850 degrees c). perovskite oxide has been widely investigated for catalyzing the oer; however, the formation of cation-enriched secondary phases at the oxide/oxide interface blocks the active sites and decreases oer performance. herein, we show that the au/yttria-stabilized zirconia (ysz) interface possesses much higher oer activity than the lanthanum strontium manganite/ysz anode. electrochemical characterization and density functional theory calculations suggest that the au/ysz interface provides a favorable path for oer by triggering interfacial oxygen spillover from the ysz to the au surface. in situ x-ray photoelectron spectroscopy results confirm the existence of spillover oxygen on the au surface. this study demonstrates that the au/ysz interface possesses excellent catalytic activity for oer at high temperatures in soecs.
