介绍了 Ba0.5Sr0.5Co0.8Fe0.2O3-delta (BSCF5582) 的热处理方法，作为增强钙钛矿催化剂电催化性能的一种方法。与未处理的钙钛矿相比，在氧气气氛中热处理制成的钙钛矿表面损失了约30 nm的尖晶石层，并表现出增强的氧还原反应和析氧反应催化活性。
A heat-treatment approach for Ba0.5Sr0.5Co0.8Fe0.2O3-delta (BSCF5582) is introduced as a way of enhancing the electrocatalytic performance of perovskite catalysts. The perovskite made by heat-treatment in oxygen atmosphere loses around 30 nm of spinel layer on the surface relative to the untreated version, and demonstrates enhanced oxygen reduction reaction and oxygen evolution reaction catalytic activities.
