A two-step synthesis of nanosheet-covered fibers based on α-Fe₂O₃/NiO composites towards enhanced acetone sensing.

ABSTRACT: A novel hierarchical heterostructures based on α-Fe₂O₃/NiO nanosheet-covered fibers were synthesized using a simple two-step process named the electrospinning and hydrothermal techniques. A high density of α-Fe₂O₃ nanosheets were uniformly and epitaxially deposited on a NiO nanofibers. The crystallinity, morphological structure and surface composition of nanostructured based on α-Fe₂O₃/NiO composites were investigated by XRD, SEM, TEM, EDX, XPS and BET analysis. The extremely branched α-Fe₂O₃/NiO nanosheet-covered fibers delivered an extremely porous atmosphere with huge specific surface area essential for superior gas sensors.
