Abstract
In recent years, the fabrication of hydrazine sensors has received extensive attention because of the toxicity of hydrazine to the environment and human beings. It is thus important to design and develop efficient electrode modifiers for the construction of hydrazine electrochemical sensors. Herein, we reported the benign synthesis of a silver (Ag)-doped zinc-based zeolitic imidazolate framework (ZIF-8). The synthesized Ag@ZIF-8 was characterized by various advanced physiochemical characterization methods, including X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDX). A screen-printed electrode (SPE) was modified with the prepared Ag@ZIF-8. The cyclic voltammetry (CV) and linear sweep voltammetry (LSV) methods were used for assessing its sensing towards hydrazine. The obtained results showed a reasonable detection limit (0.1 mM), sensitivity (1.98 mA mM cm−2), stability, selectivity, and repeatability using Ag@ZIF-8/SPE as a hydrazine sensor. The real-sample investigations demonstrated recovery rates of 96–97%.
