Abstract

The evolution of ZnO nanostructures was achieved successfully. At the initial stage, bud-shaped ZnO nanorods were prepared using sodium acetate, and then assembly of nanorods was aggregated into bulbous nanostructures.. Finally, the oval-like bulbous nanostructures were turned into ZnO nanorods and nanoflowers under the same hydrothermal reaction conditions. The as-prepared nanostructures were characterized by XRD, SEM, and HRTEM. The gas-sensing properties of both bulbous nanostructures were accounted for formaldehyde, acetone, ethanol methanol, ammonia and benzene at different concentrations and temperatures. A higher response (82, 70) and greater selectivity toward formaldehyde than other gases was observed at 75 ppm. A sharp response with the best recovery time was achieved at an optimum temperature of 200 °C.
