Abstract
ZnO nanorods were prepared by a simple hydrothermal method using Zn(NO3)2·6H2O as a precursor, NaOH as precipitant, anhydrous ethanol as solvent and ethylenediamine as a template. The morphology, size and structure were observed by scanning electron microscope, X-ray diffraction and Raman spectroscopy. The gas sensing response of ZnO nanorods to ethanol vapour was characterized by CGS-8 gas sensitivity analysis system. The results show that the response of ZnO nanorods-based gas sensor increases with the decrease of precursor concentration. The repeatability and concentration characteristics are good. The response of ZnO nanorods-based gas sensor is 33 when the concentration of Zn (NO3)2·6H2O is 0.1 mol·l−1. The optimal working temperature of the gas sensor is 275°C.
期刊介绍：
The Bulletin of Materials Science is a bi-monthly journal being published by the Indian Academy of Sciences in collaboration with the Materials Research Society of India and the Indian National Science Academy. The journal publishes original research articles, review articles and rapid communications in all areas of materials science. The journal also publishes from time to time important Conference Symposia/ Proceedings which are of interest to materials scientists. It has an International Advisory Editorial Board and an Editorial Committee. The Bulletin accords high importance to the quality of articles published and to keep at a minimum the processing time of papers submitted for publication.
