采用湿化学法制备了一种基于银功能化氧化铜纳米带的超快响应乙醇气体传感器。结果表明，Ag纳米粒子以金属Ag的形式存在于CuO纳米带的表面。在CuO纳米带表面修饰Ag纳米粒子，显著提高了其气敏性能。结果表明，Ag-CuO纳米带在室温下具有比CuO纳米带更高的响应速度和超快的响应时间特性。特别地，基于Ag-CuO纳米带的气体传感器的响应时间为约2 s，这是裸CuO纳米带的响应时间的5倍短。
An ultra-fast responding ethanol gas sensor based on the Ag-functionalized CuO nanoribbons was fabricated by a wet chemical method. Results indicated that Ag nanoparticles were on the surface of the CuO nanoribbons in the form of metallic Ag. The gas sensor performance based on CuO nanoribbons was remarkably enhanced by decorating with Ag nanoparticles. All results reveal that the Ag–CuO nanoribbons exhibit higher response and ultra-fast response time characteristic than CuO nanoribbons at room temperature. Particularly, the response time of the gas sensor based on Ag–CuO nanoribbons was about 2 s, which was five times shorter than that of the bare CuO nanoribbons.
