“…5,6 Various methods, such as spectrophotometric determination, 4, 6-9 electrochemiluminescence, 5 gas chromatography (GC) or GC tandem mass spectrometry (GC-MS), 10 and high performance liquid chromatography (HPLC) or LC-MS methods, 11,12 have been established for the detection of hydrazine. Various inorganic and organic materials with specific electrocatalytic properties have been reported, including metal nanoparticles, [14][15][16] semiconductor nanoparticles, 17,18 metallophthalocyanine complexes, 13,19,20 hexacyanoferrate salt, 21 and organic compounds with a hydroquinone structure. Therefore, it is urgent to develop a simple but reliable and sensitive method for the detection of hydrazine hydrate at trace levels in aqueous solution.…”

In this study, a novel mercapto-terminated trinuclear Ni(II) complex (Ni3) was synthesized and used as electrocatalysts for the detection of hydrazine hydrate in real water samples. The as-prepared Ni3 molecules possess six thiomethyl groups at the periphery of the complex;such SCH 3 groups can react with Au electrodesto immobilize the Ni3 molecules on their surface through the formation of a self-assembled monolayer. The Ni3-modified Au electrode (Ni3/Au) demonstratedits excellent electrocatalytic activity for the oxidation of hydrazine hydrate through the significant decrease in the overpotential.Chronoamperometry study showed a diffusion coefficient (D) of 5.82×10 −5 cm 2 ·s −1 and acatalytic rate constant of 8.57×10 3 M −1 ·s −1 . Using square wave voltammetry (SWV) technique, this Ni3/Au electrodebased hydrazine hydratesensor exhibiteda high sensitivity in quantitive analysis, and the detection limit could be as low as ~0.07 μM with a linearity ranging from 0.2 to 50 μM. Additionally, the good reproducibility, anti-interference performance, and long-term stability made the proposedsensor be capable of detecting trace level of hydrazine hydrate in real water samples.

Co3O4 nanoparticles (NPs) were synthesized and decorated on the multi‐walled carbon nanotubes (MWCNTs) through a simple hydrothermal procedure. The deposited Co3O4 NPs on the sidewalls of MWCNTs were found to be cubic crystal structure and homogenously dispersed with a narrow particle size distribution centered at around 6 nm. The Co3O4/MWCNTs nanocomposite was then utilized for the electrochemical detection of hydrazine, and exhibited a high sensitivity of 34.5 µA mM−1, a low detection limit of 0.8 µM (S/N=3), a wide linear range of 20 µM to 1.1 mM along with a short response time of less than 5 s.
