Abstract

Abstract One dimensional (1D) Ca₂Co₂O₅ with hierarchical structure has been fabricated by electrospinning successfully for the first time. The formation process of hierarchical structure Ca₂Co₂O₅ are investigated by powder X-ray diffraction and scanning electron microscopy. High Seebeck coefficient (maximum value of 191 μV K^-1) and power factor (maximum value of 1.85×10^-4 W m¹ K^-2 at 963 K) could be realized by fabricating 1D hierarchical structure assembled by nanoplates. This work provides a step forward in the design of other materials with similar layered building blocks in the crystal structure.
