چکیده
In this study, by using a co-precipitation method MoO3/CuO/ZnO nanocomposite material was synthesized. Then the prepared fully characterized XRD (X-ray diffraction), SEM (scanning electron microscopy), EDS (energy dispersive x-ray spectroscopy), CV (cyclic voltammetry), and EIS (Electrochemical Impedance Spectroscopy). Zeta potential hydrodynamic size were measured Zetasizer in PBS buffer. By Scherrer's formula from XRD, particle determined which around 26.5 nm. For promising chemical sensor development, fabricated onto glassy carbon electrode (GCE) to provide probe with fast response towards selective hydrazine (HZ) toxin phosphate buffer phase. The is exhibited good sensitivity long-term stability as well enhanced electrochemical performances. A calibration plot found linear range of 0.2 nM 2.0 mM (linear dynamic range, LDR) presence aqueous HZ solutions highest value lower limit detection quantification (LOQ). This approach an efficient technique developing highly effective ternary metal oxides for detecting environmental pollutants on broad scale.

متن کاملHighly sensitive hydrazine chemical sensor based on ZnO nanorods field-effect transistor.
A highly sensitive hydrazine chemical sensor has been fabricated based on a field-effect transistor (FET) by growing vertically-aligned ZnO nanorods directly on silver electrodes. The FET sensor showed a high sensitivity and a low limit of detection (LOD) of 59.175 μA cm(-2)μM(-1) and ~3.86 nM, respectively. This demonstrates a cost effective and low power consuming FET strategy for the detecti...
