摘要
选用木棉生物质作为管状模板,通过Zn(NO_(3))_(2)水溶液的简单浸渍和空气煅烧工艺,成功制备出2个具有仿生结构的ZnO微管材料,其中,经过600℃煅烧得到的ZnO-600微管由均匀的小尺寸纳米粒子组装而成。气敏测试结果显示:ZnO-600传感器在低的92℃操作温度下对10μL·L^(-1)NO_(2)气体的响应值达到39.3,响应/恢复时间分别为64 s/40 s,检测限低至0.5μL·L^(-1)。此外,它还展现出高选择性、良好的重现性、抗湿性以及长期稳定性,进而在环境监测有害的NO_(2)气体方面具有潜在的应用前景。
Kapok biomass was selected as the tubular template,and two ZnO microtubular materials with biomimetic structure were successfully prepared by simple impregnation of Zn(NO_(3))_(2) aqueous solution and air calcination process.Thereinto ZnO-600 microtubules obtained by 600℃calcination were assembled from uniformly small-sized nanoparticles.Gas sensitivity test results show that the ZnO-600 sensor achieves a response value of 39.3 for 10μL·L^(-1) NO_(2) gas at low operating temperature of 92℃,with a response/recovery time of 64 s/40 s,and detection limit as low as 0.5μL·L^(-1).In addition,it exhibits high selectivity,good reproducibility,humidity resistance,and long-term stability.Thus it has potential application in environmental monitoring of harmful NO_(2) gas.
