Electrospun nanofibers of ZnO/BaTiO3 heterostructures with enhanced photocatalytic activity

► BaTiO3 nanofibers were prepared by electrospinning method. ► Dispersed ZnO nanoparticles were grown on BaTiO3 nanofibers. ► ZnO/BaTiO3 nanofibers show excellent performance of the photocatalytic property.
