摘要: 利用Zn(NO₃)₂·6H₂O、Al(NO₃)₃和(CH₂)₆N₄为反应物,PEG400为表面活性剂,通过共沉淀法制备了Al³⁺掺杂的花状氧化锌纳米棒结构。Al³⁺掺杂会调控所得氧化物的微结构,提高材料的气敏性能。在350 ℃工作温度下,掺杂0.3wt%Al³⁺的花状氧化锌微结构对0.200 mL·L^-1乙醇的灵敏度达28,响应时间仅12 s。

Abstract: Flowerlike ZnO nanostructure was synthesized via a co-precipitation method by using Zn(NO₃)₂·6H₂O, Al(NO₃)₃ and (CH₂)₆N₄ as reactants, PEG400 as a surfactant. The obtained ZnO nanostructures can be tuned by the added Al³⁺ in the above process, resulting in an increase of gas-sensing response. The gas-sensing response of 0.3wt% Al³⁺-doped ZnO nanostructure reaches 28 to an ethanol concentration of 0.200 mL·L^-1, with a response time of only 12 s at the working temperature of 350 ℃.
