Morphology, crystal structure and electronic state one-step co-tuning strategy towards developing superior perovskite electrocatalysts for water oxidation†
Abstract
Here, we use an electrospinning method to control the crystal structure, electronic structure and microstructure of catalysts simultaneously. The electrospun perovskite SmBa0.5Sr0.5Co2O6−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.
