Following a facile two‐step synthetic route (electrospinning and subsequent calcination), highly porous Mn 2 O 3 nanofibers (Ø 105 nm) were fabricated. The as‐prepared Mn 2 O 3 nanofibers were applied to construct an amperometric sensor for hydrazine detection in neutral phosphate buffer. The developed hydrazine sensor showed a fast response time (within 5 s), a wide linear range up to 644 µM, a high sensitivity of 474 µA mM −1 cm −2 , a good limit of detection of 0.3 µM ( S / N =3) as well as good reproducibility and selectivity. These results demonstrate that Mn 2 O 3 nanofibers have great potential in the application of hydrazine detection.
