Morphology, crystal structure and electronic state one-step co-tuning strategy towards developing superior perovskite electrocatalysts for water oxidation

Here, we use an electrospinning method to control the crystal structure, electronic structure and microstructure of catalysts simultaneously. The electrospun perovskite SmBa_0.5Sr_0.5Co₂O_6-δ (SBSC) possesses not only a large specific surface area but also an optimized crystal structure and electronic state, showing an excellent OER activity and durability.
