Abstract
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.

A successful hydrazine derivative material with zinc oxide nano-urchins is reported and exhibited the good sensitivity as well as lower detection limit[17]. Another hydrazine derivate material based on silver-doped zinc oxide was reported, which was successful with high sensitivity and detection limit[18]
Selective 3-MPHyd chemical material based on nano-formulated CuO/MnO2/Gd2O3 spike was fabricated and reported in details
Summary
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 ternary combination of CuO/MnO2/Gd2O3 NSs may be an effective detection material to detect environmental toxins due to the large active surface area in their interior or exterior surfaces Various toxic analytes such as phenols and their derivatives, alcohol, acetone, ammonium hydroxide, dichloromethane, heavy-metal ions, hydrazine, aliphatic and aromatic compounds have been detected by various compositions of metal oxide/ sulphides with the doped or un-doped, mixed/dual combinations[19]. CuO/MnO2/Gd2O3 NS nanostructured materials have employed a great deal of consideration due to their chemical, structural, physical, and optical properties in terms of large-active surface area, high-stability, and high porosity These properties are directly depend on the structural morphology prepared by reactant precursors for making the CuO/MnO2/Gd2O3 porous materials in the basic medium at low-temperature. CuO/MnO2/Gd2O3 NS material offers improved performance due to the large-active surface area, which increased conductivity and current responses of the CuO/ MnO2/Gd2O3 NSs/Nafion/GCE assembly during the electrochemical investigation
