Hydrazine has been identified as a carcinogenic mutagenic, hepatotoxic, and neurotoxin material. A metal-organic framework with tetragonal symmetry, DMOF-1 (Zn2(bdc)2dabco) was synthesized by a versatile and facile technique, followed by its efficient development and validation as hydrazine electrochemical sensor. Differential pulse voltammetry (DPV), linear sweep voltammetry (LSV), and cyclic voltammetry (CV) techniques were used as diagnostic techniques. In this study, scanning electron microscopy (SEM) and x-ray diffraction (XRD) were used to characterize the MOF. In the electro-oxidation of hydrazine, there was a highly catalytic activity shown by the modified electrode. In addition, there was a greater signal response, compared to the unmodified electrode, which was primarily because DMOF-1 offered the establishment of large active surface area. Also, the detection limit for hydrazine, linear range, and sensor sensitivity were reported to be 0.02 µM, 0.09-400.0 µM, and 0.0863 µA/µM-1, respectively. Ultimately, the amplified sensor was able to properly analyze hydrazine in different samples of water.
