HRGO–Co@SnO2 Nanocomposite for Electrochemical Detection of Hydrazine
- 13 Downloads
A low-cost modified electrode using bimetallic nanoparticles (Co@SnO2) and honey reduced graphene oxide (HRGO) has been developed for detecting trace amounts of hydrazine. The HRGO and Co@SnO2 nanoparticles were prepared using a natural reducing agent, honey. The synthesized nanoparticles and nanocomposite (HRGO–Co@SnO2) were characterized by Fourier transform infrared (FT-IR) spectroscopy, x-ray diffraction (XRD) studies, scanning electron microscopy (SEM) and Energy dispersive spectroscopic analysis (EDA). The electrocatalytic ability of the modified glassy carbon electrode (GCE) to detect hydrazine was investigated. The modified electrode exhibited a wide linear range of (0–50 μL) to detect hydrazine and had a low detection limit of 10 μL. This modified electrode had superior sensing performance compared to previously reported electrodes and also exhibited good repeatability, reproducibility, stability and ease of operation.
