Abstract
In this paper, the ZnO nanostructures were synthesized by electrospinning technique, and an improvement of the gas-sensing property of the ZnO nanostructures by calcination time was reported. The porous network-like ZnO nanostructures (12Â h) were observed from the SEM micrographs. The PL revealed that the porous network-like ZnO nanostructures had more donor defects (oxygen vacancy) which were good for gas sensing performance. Gas sensing properties revealed that the porous network-like ZnO nanostructures exhibited a higher response and fast response to acetone vapor and excellent selectivity, which was attributed to porous network structure and oxygen vacancies. The acetone sensing mechanism of the porous network-like ZnO nanostructures was also discussed.
