In the present research, ZnO@TiO2 nanoparticles (ZnO@TiO2 NPs) was synthesized by using a simple method and results of infrared (IR), X-ray diffraction (XRD), field emission scanning electron microscope (FE-SEM), energy-dispersive spectroscopy (EDX) confirmed their synthesis. Then, an electrochemical sensor based on screen printed graphite electrode (SPGE) modified with NPs developed for voltammetric detection hydrazine in water samples. The SPGE demonstrates significant performance toward due to synergistic effect between ZnO TiO2 it proved from cyclic voltammetry (CV). Also, observation oxidation peak without reduction opposite scan direction indicated irreversibility both bare ZnO@TiO2/SPGE. Under optimized conditions (pH differential pulse parameters), current response at ZnO@TiO2/SPGE showed linear dependence concentration, ranging 0.01 µM 585.0 limit (LOD) 0.005 µM. addition, pertinency practical applications investigated quantification findings recovery values 97.3% 104.2% relative standard deviations (RSDs) ≤ 3.5% river tap

From e-waste to eco-sensors: synthesis of reduced graphene oxide/ZnO from discarded batteries for a rapid electrochemical bisphenol A sensor

RSC Advances, Journal Year: 2024, Volume and Issue: 14(48), P. 36073 - 36083

Published: Jan. 1, 2024

Improper disposal of used dry cell batteries and the leaching bisphenol A (BPA), a prevalent endocrine disruptor present in food packaging, into surface water pose significant threat to both environment drinking water, threatening sustainability ecosystem. Thus, it is imperative manage detrimental e-waste regularly monitor BPA using sensitive reliable technique. This study proposes cost-effective reduced graphene oxide/zinc oxide (rGO/ZnO) nanohybrid, entirely synthesized from electronic waste, for electrochemically detecting an aqueous medium. Graphite metallic Zn precursors obtained discarded were employed synthesize rGO/ZnO. The successful characterization prepared rGO rGO/ZnO nanohybrid was conducted through different state-of-the-art techniques. An rGO/ZnO-modified glassy carbon electrode (GCE) exhibited superior conductivity larger area. Voltammetric at GCE successfully detected medium, demonstrating one-electron proton pathway oxidation. sensor demonstrated linear response within concentration range 1-30 μM, with limit detection 0.98 nM sensitivity 0.055 μA μM
