Abstract
Monodisperse ZnO hollow six-sided pyramids were successfully synthesized by a low-cost and simple hydrothermal method at 160°C for 20h without the use of any surfactant or template. The sodium citrate (Na3C6H5O7·2H2O) and glycerol (C3H8O3) played a pivotal role in the growth of hollow six-sided pyramid, and the possible growth mechanism was also proposed based on the experimental facts. Moreover, the gas sensor based on this structure displayed excellent gas sensing properties to ethanol at the optimum operating temperature of 240°C. The response was about 187 and the response-recovery time was around 11 and 9s for 200ppm ethanol, respectively, which indicated that this structure had high sensitivity, fast response-recovery time and good selectivity to ethanol.
