Source abstract
Abstract
通过溶剂热法(无水乙醇)制备了Cu 2+ (0~6mol%)掺杂ZnO纳米棒粉体, 采用X射线衍射仪和扫描电镜对掺杂ZnO纳米粉体的晶体结构和微观形貌进行了表征. 研究了Cu 2+ 掺杂比例、溶剂热反应温度及时间对材料气敏性能的影响; 考察ZnO(120℃, 10 h)和3mol% Cu 2+ 掺杂ZnO(120℃, 10 h)粉体对应元件对甲醛、乙酸、甲苯、乙醇、丙酮、三甲胺等六种气体的气敏性能. 结果表明: 通过溶剂热法制备的ZnO粉体为纳米棒状结构, 棒长度和直径随Cu 2+ 掺杂比例不同发生变化; 3mol% Cu 2+ 掺杂ZnO(120℃, 10 h)样品对应元件对低浓度乙醇有很好的选择性, 在395℃工作温度下对1×10 –3 乙醇的灵敏度为380.5, 响应恢复时间分别为5 s和40 s, 对1×10 –6 乙醇的灵敏度可达4.2.
