Synthesis, Characterization and Sulfur Dioxide Sensing Performances of Hierarchical Zinc Oxide Nanorods Based Sensor

Abstract:

Zinc oxide nanostructures were successfully synthesized via a facile hydrothermal method. Structural characterizations by means of X-ray diffraction and field emission scanning electron microscopy were conducted, and the as synthesized products composed of numerous nanorods have a hierarchical flower-type structure. The optimum operating temperature of the sensing material to sulfur dioxide is about 270 °C, and the linear correlation coefficient of the sensing material to sulfur dioxide gas is equal to 0.978. Furthermore, this sensing material demonstrates reversible sensing response and rapid response-recovery characteristic to sulfur dioxide. All results indicate our products a promising sensing material for recognition of sulfur dioxide.
