Al-Ce co-doped BaTiO nanofibers as a high-performance bifunctional electrochemical supercapacitor and water-splitting electrocatalyst.

Supercapacitors and water splitting cells have recently played a key role in offering green energy through converting renewable sources into electricity. Perovskite-type electrocatalysts such as BaTiO, have been well-known for their ability to efficiently split water and serve as supercapacitors due to their high electrocatalytic activity. In this study, BaTiO, Al-doped BaTiO, Ce-doped BaTiO, and Al-Ce co-doped BaTiO nanofibers were fabricated via a two-step hydrothermal method, which were then characterized and compared for their electrocatalytic performance.
