Following a facile two‐step synthetic route (electrospinning and subsequent calcination), highly porous Mn2O3 nanofibers (Ø 105 nm) were fabricated. The as‐prepared Mn2O3 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...
A glassy carbon electrode modified with palladium/gold nanoparticles was successfully prepared by an electrodeposition process. It efficiently oxidizes hydrazine at a low overpotential of −0.26 V versus SCE. The Pd‐AuNPs with an average size of 50–80 nm are uniformly dispersed at the GCE. The Pd‐AuNPs/GCE was used for determination of hydrazine in phosphate buffer solution of pH 7.0. The amperometric...
