Abstract

In order to improve the gas-sensing performance of ZnO, a novel peony shaped ZnO stacked with nanosheets were prepared using hydrothermal method, and the obtained ZnO was characterized and tested for gas sensitivity. The results showed that the particle distribution of the peony shaped ZnO was uniform, with a particle size of about 0.8 μm. The gas-sensing response test results show that the peony shaped ZnO has excellent selectivity to ethanol gas. When the concentration of ethanol gas is 100 ppm, the gas-sensing response of the peony shaped ZnO to ethanol gas reaches 17.4, and the response time and recovery time are 8 s and 12 s, respectively. Even at an ethanol gas concentration of 2 ppm, the gas-sensing response of the peony shaped ZnO to ethanol gas can reach 2.1. Compared to existing literature reports, the peony shaped ZnO prepared in this paper has better gas-sensing performance. This study will provide data support and theoretical reference for the development of high-performance gas sensors.

新型牡丹形氧化锌及其优异的乙醇气体传感性能

为了提高氧化锌的气敏性能，采用水热法制备了一种新型的牡丹形氧化锌叠层纳米片，并对得到的氧化锌进行了表征和气敏测试。结果表明，牡丹形氧化锌的颗粒分布均匀，粒径约为 0.8 μm。气敏响应测试结果表明，牡丹形氧化锌对乙醇气体具有极佳的选择性。当乙醇气体浓度为 100 ppm 时，牡丹形 ZnO 对乙醇气体的气敏响应达到 17.4，响应时间和恢复时间分别为 8 秒和 12 秒。即使乙醇气体浓度为 2 ppm，牡丹形 ZnO 对乙醇气体的气敏响应也能达到 2.1。与现有文献报道相比，本文制备的牡丹形 ZnO 具有更好的气敏性能。该研究将为高性能气体传感器的开发提供数据支持和理论参考。
