Developing effective non-noble metal electrocatalysts for the oxygen evolution reaction (OER) remains challenging due to limited active sites and poor electronic conductivity in mixed oxide catalysts. To address these limitations, a one-step spray drying method is employed synthesize hierarchical La0.8Sr0.2CoO3 supraparticles (LSCO-SP) from high-surface-area nanoparticles (LSCO-NP). LSCO-SP demonstrate significantly enhanced OER performance, requiring ~300 mV lower overpotential at 100 mA...
Abstract Despite considerable efforts to develop electrolyzers for energy conversion, progress has been hindered during the implementation stage by different catalyst development requirements in academic and industrial research. Herein, a coherent workflow efficient transition of electrocatalysts from basic research application readiness alkaline oxygen evolution reaction is proposed. To demonstrate this approach, La 0.8 Sr 0.2 CoO 3 selected as catalyst, its electrocatalytic performance...
