제목 Fabrication of electrochemical sensor using Hollow ZnO Spheres for Hydrazine Detection
초록 This work reports the synthesis of hollow sphere zinc oxide (HS-ZnO) nanostructures by simple and economical hydrothermal method for the effective detection of toxic hydrazine chemical via electrochemical sensor. The ethylene glycol (EG) and ethanol as solvents played a significant role to achieve the HS-ZnO nanostructure. The crystalline and structural analysis evidenced that the synthesized nanomaterials were well–crystalline with typical wurtzite ZnO crystal. The electrode was fabricated for the detection of different concentrations of hydrazine chemical through an electrochemical analysis. Herein, HS-ZnO based electrode exhibited a high sensitivity of ~361.2 μA.mM-1.cm-2, a good detection limit of ~20.8 nM and short response time of 10 s with correlation coefficient (R) of ~0.97752. Thus, HS-ZnO nanostructures electrode could be used as an efficient electron mediator for the fabrication of various effective chemical sensors.
