Nanorods of ZnO: An effective hydrazine sensor and their chemical properties

Abstract

In this paper, ZnO nanorods (ZnONRs) have been synthesized via chemical solution approach. The chemicals such as the nitrate salt of zinc, hexamethylenetetramine and NaOH were utilized and the acquired solution was refluxed at ∼90 °C for 60 min for fabrication of nanorods. Thereafter, the obtained NRs were well characterized with the instruments such as X-ray diffraction pattern (XRD), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM) and Fourier transform infra-red (FTIR) spectroscopy also with electrochemical data. The well crystalline nanorods were used as an electrode material for to high sensitive hydrazine sensor detection with glassy carbon electrode (GCE). The cyclic voltammetry (CV) data's were analyzed from low (2μL/100 mL PBS) to high concentration (1–5 mL/PBS) of hydrazine with NRs/GCE electrode. The electrochemical impedance spectroscopy (EIS) was evaluated from 0 to 5 mL of solution at 4211 Z/ohm conditions. The proposed sensor and their stability are the promising features of the sensor.
