“…On the other hand the irreversible oxidation of hydrazine is kinetically slow and require high overpotential at carbon electrodes. Modified electrodes can be minimized hydrazine overpotential, and accelerated electron transfer rate for the detection of hydrazine [1,18,19].…”

This study reports a detailed analysis of an electrode material containing poly(phenolphthalein), carbon nanotubes and gold nanoparticles which shows superior catalytic effect towards to hydrazine oxidation in Britton–Robinson buffer (pH 10.0). Glassy carbon electrode was modified by electropolymerization of phenolphthalein (PP) monomer (poly(PP)/GCE) and the multiwalled carbon nanotubes (MWCNTs) was dropped on the surface. This modified surface was electrodeposited with gold nanoparticles (AuNPs/CNT/poly(PP)/GCE). The fabricated electrode was analysed the determination of hydrazine using cyclic voltammetry, linear sweep voltammetry and amperometry. The peak potential of hydrazine oxidation on bare GCE, poly(PP)/GCE, CNT/GCE, CNT/poly(PP)/GCE, and AuNPs/CNT/poly(PP)/GCE were observed at 596 mV, 342 mV, 320 mV, 313 mV, and 27 mV, respectively. A shift in the overpotential to more negative direction and an enhancement in the peak current indicated that the AuNPs/CNT/poly(PP)/GC electrode presented an efficient electrocatalytic activity toward oxidation of hydrazine. Modified electrodes were characterized with High-resolution transmission electron microscopy (HRTEM), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and electrochemical impedance spectroscopy (EIS). Amperometric current responses in the low hydrazine concentration range of 0.25–13 µM at the AuNPs/CNT/poly(PP)/GCE. The limit of detection (LOD) value was obtained to be 0.083 µM. A modified electrode was applied to naturel samples for hydrazine determination.

“…Various techniques such as titrimetry, flow injection analysis, spectrophotometry, amperometry, ion chromatography, and chemiluminescence have been used for the determination of hydrazine (Gilbert, Rioux, and Saheb 1984;Budkuley 1992;Safavi and Karimi 2002;Ebadi 2003;Safavi, Abbasitabar, and Nezhad 2007;Jayasri and Narayanan 2007). Electrochemical methods are relatively fast, simple, and inexpensive; however, hydrazine oxidation is generally slow at carbon electrodes and requires a relatively high overpotential at bare electrodes (Ozoemena and Nyokong 2005;Zheng and Song 2009;Koçak, Aslışen, and Koçak 2015). Chemically modified electrodes are good candidates to overcome this problem (Li and Lin 2007).…”

L-serine monomer was polymerized electrochemically on a glassy carbon electrode by cyclic voltammetry. After L-serine polymerization, gold and platinum metal nanoparticles were doped by electrochemical reduction on the surface. The modified electrodes were characterized by Downloaded by [UQ Library] at 23:20 13 June 2015 2 using scanning electron microscopy and electrochemical impedance spectroscopy. The electrochemical behavior of hydrazine oxidation at the electrodes was investigated in 0.1 M pH 7.0 phosphate buffer. Hydrazine oxidation peaks were observed at 650, 399, 280, and 395 mV at the bare glassy carbon , poly(L-serine) modified glassy carbon, gold nanoparticle modified poly(L-serine) film glassy carbon electrode, and platinum nanoparticles modified poly(L-serine) film glassy carbon electrode, respectively. The most active surface towards hydrazine oxidation was the platinum nanoparticle modified poly(L-serine) film glassy carbon electrode with a 1045 mV negative potential shift and approximately three-fold higher peak current. The hydrazine oxidation peak was shifted to a 370 mV negative potential with a 2.5 times higher current at the gold nanoparticle modified poly(L-serine) film glassy carbon electrode compared to the bare electrode. The linear concentration ranges were from 1.0 to 1000 µM and 0.5 to 1000 µM for the gold nanoparticle modified poly(L-serine) film glassy carbon and the platinum nanoparticles modified poly(L-serine) film glassy carbon electrodes with limits of detections of 0.5 and 0.2 µM, respectively.

An electrochemical sensor was fabricated by construction of nickel nanowires on the surface of poly(p‐aminophenol) (PPAP) modified glassy carbon electrode. The electrochemical response of dicofol, a known pesticide and used for agricultural activities such as cyclic voltammetry and differential pulse voltammetry, were investigated and the results were compared with those obtained unmodified electrodes. Following the optimization of NaOH concentration, polymerization cycle number, Ni nanowire amount, the linear range for the dicofol was studied and found as 0.83–30.7 μmol L−1 (R2=0.9981) at Ni/PPAP/GCE with a 0.08 μmol L−1 detection limit according to S/N=3. Finally, the proposed Ni/PPAP/GCE sensor was successfully applied for the dicofol analysis in soil samples. The characterization of the developed surface was carried out by scanning electron microscopy and X‐Ray photoelectron spectroscopy.
