These industries discharge various pollutants in gas and liquid form to the environment which are responsible for the environmental pollution [5–7]. One of
these pollutants is waste liquid which causes contamination, eutrophication, and perturbation in aquatic life. Waste liquid discharges various organic pollutants to the environment such as hydrazine derivatives, liquid ammonia, dyes, phenols, etc. Hydrazine and its derivatives such phenyl hydrazine are well-known organic pollutant and industrial MGCD0103 purchase chemicals which discharge to the environment from their uses in industries and as aerospace fuels [16, 17]. It is one of the great challenges to control these pollutants in the environment and protect the human and aquatic life. Various techniques and materials have been used to develop susceptible and consistent analytical technique to monitor and protect the environment from toxic nature of phenyl hydrazine. Among these techniques, electro-analytical method using various redox mediators has proven itself as one of the simple and well-organized technique for the recognition of various pollutants [10–12]. Here, we proposed ZnO composite nanorods as a sensor material for the detection of phenyl hydrazine by electroselleck inhibitor Chemical method to overcome the lower over potential of the conventional electrode and show good
performance in terms of sensitivity by improving electrochemical oxidations. Metal oxide nanostructures Batimastat solubility dmso have been used as a redox mediator Astemizole to overcome the lower over potential of the conventional electrodes
used in electro-analytical method and have shown good performance in terms of sensitivity by improving electrochemical oxidations [1–3]. Several reports in literature are related to pure and doped nanomaterials, but there is no literature about electrochemical properties of composite nanomaterials for phenyl hydrazine detection in aqueous phase. To get the utmost profit of the assets of nanomaterial, several methods have been established. However, we have used simple, low-cost, and low-temperature hydrothermal method for the synthesis of composite nanorods. The aim of this involvement was to prepare, characterize, and investigate chemical sensing performance of composite nanorods based on Ag/Ag2O3/ZnO. The morphological, structural, and optical properties of the prepared nanorods were characterized by field emission scanning electron microscopy (FESEM), X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), and ultraviolet–visible (UV–vis) spectroscopy. Chemical sensing property was studied by simple I-V technique and detected phenyl hydrazine in aqueous solution with high sensitivity and selectivity.
