| 摘要 |
The present invention relates to a chemical sensor for detection of hydrazine. The invention detects hydrazine with a modified electrode using ZnO nanostructures such as nanonails and hexagonal-shaped nanorods by electrochemical analysis. The ZnO nanostructures are grown by simple non-catalytic thermal evaporation process in the presence of oxygen and coated on the surface of electrode. The prepared ZnO nanostructures/electrode is used as electron mediator and enhances the electron transfer between the hydrazine and electrodes and produces a high sensitivity. The most important target of this invention is to present the use of novel, cost effective and easily grown ZnO nanostructures as efficient electron mediators to modify the electrodes and fabricate the chemical sensor for effective detection of hydrazine. |
