“…Hence, NiCo/GCE can be hopefully regarded as a newly designed option for HZ electro-chemical detection. 80 In their study, Faisal et al designed an electro-chemical procedure in order to rapidly and effectively detect HZ by means of the polythiophene (PTh)/ZnO nanocomposite modi-ed GCE. Then, a modied sol-gel process through the F127 structure directing mediator accompanied by a chemical oxidative polymerization procedure has been used to synthesize PTh/ZnO nanocomposite.…”

“…It is considered one of the poisonous chemicals even at low concentration and is very hazardous to living organisms. The potential symptoms of hydrazine exposure range from eye and nose irritation, pulmonary edema, skin dermatitis, temporary blindness and serious damage to many human organs such as the kidney and liver [3][4][5]. Due to its mutagenic and carcinogenic behavior, it has been cited in the Environmental Protection Agency (EPA) list.…”

Herein, we report the fabrication of a modified glassy carbon electrode (GCE) with high-performance hydrazine sensor based on Fe-doped TiO 2 nanoparticles prepared via a facile and low-cost hydrothermal method. The structural morphology, crystalline, crystallite size, vibrational and scattering properties were examined through different characterization techniques, including FESEM, XRD, FTIR, UV-Vis, Raman and photoluminescence spectroscopy. FESEM analysis revealed the high-density synthesis of Fe-doped TiO 2 nanoparticles with the average diameter of 25 ± 5 nm. The average crystallite size of the synthesized nanoparticles was found to be around 14 nm. As-fabricated hydrazine chemical sensors exhibited 1.44 µA µM −1 cm −2 and 0.236 µM sensitivity and limit of detection (LOD), respectively. Linear dynamic ranged from 0.2 to 30 µM concentrations. Furthermore, the Fe-doped TiO 2 modified GCE showed a negligible inference behavior towards ascorbic acid, uric acid, glucose, SO 4 2− , NO 3 − , Pb 2+ and Ca 2+ ions on the hydrazine sensing performance. Thus, Fe-doped TiO 2 modified GCE can be efficiently used as an economical, easy to fabricate and selective sensing of hydrazine and its derivatives.

“…The bare FTO and bimetallic Pt catalyst lack catalytic stability with poor sensing performance. The catalytic capacity of the ternary metal catalyst is much higher than the bimetallic or bare FTO electrode [30]. It was observed that with the increase of scan rate, the current is also increased (Figure 4a).…”

The simple and effective method for the novel synthesis of Pt‐based nanoparticle was presented with high efficiency. The sensitive catalyst for the simultaneous detection of catechol and hydroquinone was prepared by depositing ternary metal complex on fluorine‐doped tin‐oxide (FTO). The composition and morphology of nanomaterials were characterized by TEM, HRTEM, XRD, XPS, and EDS (energy dispersive spectroscopy). The size of the Pt‐based nanomaterial was about 5±1 nm. The electrochemical performance of the modified catalyst was studied by CV, DPV, and EIS. The modified PtNiCu@FTO catalyst possessed good electro‐oxidation activity for hydroquinone and catechol and used for simultaneous detection of catechol and hydroquinone at scan rate of 20 mV s−1 (vs. Ag/AgCl). Detection responses were found in the ranges of 5–2900 μM for hydroquinone and 5–3000 μM for catechol. The detection limits (LOD) for HQ and CC were observed as 0.35 and 0.29 μM, respectively. The sensitivity of HQ and CC were 1515.55 and 1485 μA mM−1 cm−2, respectively. The prepared nanomaterial were effectively applied for the determination of CC and HQ in real samples.
