Description

A new hydrazine electrochemical sensor was fabricated based on in situ synthesis of Cu3(BTC)2/GO nanocomposite. Cu3(BTC)2/GO composite were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and Fourier transform infrared spectrometry (FT-IR). Meanwhile, the electrochemical behaviors of hydrazine on the Cu3(BTC)2/GO/GCE were studied by cyclic voltammetry and linear sweep voltammetry. Under the optimized conditions, Cu3(BTC)2/GO/GCE had enhanced electrocatalytic activity toward hydrazine due to synergic catalytic effect between Cu3(BTC)2 and GO. The electrochemical sensor exhibited a wider linear range (1.0 µM to 5000 µM) and a lower detection limit (0.5 μM) as well as good reproducibility and stability. The proposed sensor has also been used for the determination of hydrazine in tap water with satisfactory results.
