“…Thus, the use of Na on on the modi ed GCE improves the conductance and the electron transfer rate of the resultant sensor. The similar characteristic of the sensor assembled using Na on has reported in several articles to detect toxic chemicals [47][48][49][50][51] The toxic chemicals in analytical grade such as benzaldehyde, 4-AP, 4-NPHyd, 2,4-DPDHCl, 3-CP, 3-MP, M-THydHCl, zimtaldehyde, 4-MP and 3-MPHydHCl were subjected to I-V investigation by assembled sensor based on ZnO/SnO2 NPs/GCE at rst illustrated in Fig. 3(a).…”

The 4-NPHyd (4-nitrophenylhydrazine) electrochemical sensor assembled using wet-chemically prepared ZnO/SnO2 nanoparticle (NPs) decorated a glassy carbon electrode (GCE) with conductive Nafion binder. The synthesized NPs characterized by XPS, ESEM, EDS, and XRD analysis. The calibration of the proposed sensor obtained from current versus concentration of 4-NPHyd found linear over a concentration (0.1nM~0.01mM) of 4-NPHyd, which denoted as the dynamic range (LDR) for detection of 4-NPHyd. The 4-NPHyd sensor sensitivity calculated using the LDR slope considering the active surface of GCE (0.0316 cm2), which is equal to be 7.6930 µAµM-1cm-2, an appreciable value. The detection limit (LOD) at signal/noise (S/N=3) estimated, and outstanding lower value at 94.63±4.73 pM perceived. The analytical parameters such as reproducibility, long-term performing ability and response time are found as appreciable. Finally, the projected sensor shows exceptional performances in the detection of 4-NPHyd in environmental samples.

“…Such ndings suggested that their CdO/CNT nanocomposite would be a hopeful electro-chemical sensor to detect dangerous toxins in order to largely cleanse the environment. 76 In their study, Huang et al dealt with anchoring CeO 2encapsulated Au NPs to the RGO (RGO/Au@CeO 2 ) by an interfacial autoredox reaction in a solution consisting of tetrachloroauric acid and Ce(III) on a solid support. Then, the produced material has been inserted on a GCE and has been utilized as one of the electro-chemical HZ sensors at the trace levels.…”

“…9-11). These reactions are taken place in bulk-solution or air/liquid interface or surrounding air due to the low carrier concentration, which probably increased the resistance of ternary material surface as well as decreased the conductivity [53][54][55][56] . The anlayte 3-MPHyd sensitivity towards CuO/MnO 2 /Gd 2 O 3 NSs could be attributed to the high oxygen deficiency and defect the density leads to increase the oxygen adsorption for form active as O 2 -, then Oand finally OH -.…”

In this approach, thin spikes (NSs) of ternary nano-formulated mixed CuO/MnO2/Gd2O3 were synthesized by the hydrothermal approach for efficient detection of 3-methoxyphenyl hydrazine (3-MPHyd) chemical from various environmental samples. The NSs were systematically characterized by using XPS, EDS, TEM, FTIR, UV/vis, and XRD. The fabricated NSs onto the glassy carbon electrode (GCE) was successfully applied for the selective and sensitive detection of 3-MPHyd in the phosphate buffer system (PBS), which displayed the highest sensitivity, good selectivity with ultra-trace detection limit, high stability, good reproducibility, and quick response time. The real environmental samples were tested for validation from stand point of the ternary doped nanomaterials for sensing in the practical applications using by electrochemical method.
