Abstract

Networked ZnO nanowires were fabricated via a vapor-phase selective growth method. Pt nanoparticles were functionalized on the networked ZnO nanowires. In this study, for the functioanlization, γ-ray radiolysis was applied. By the method, Pt nanoparticles of - 10 nm in diameter were uniformly anchored on the surface of each ZnO nanowire. The sensing properties of the Pt-functionalized, networked ZnO nanowires were investigated in terms of NO2, CO and benzene at 100 degrees C. The sensing capability of the Pt-functionalized ZnO nanowires at that temperature supports their potential use in chemical gas sensors.

摘要

通过气相选择性生长法制备了网络化的氧化锌纳米线。在网络化的氧化锌纳米线上对铂纳米颗粒进行了功能化处理。在本研究中，采用γ射线辐射分解法进行功能化处理。通过该方法，直径为 - 10纳米的铂纳米颗粒均匀地锚定在每根氧化锌纳米线的表面。在100摄氏度下，对铂功能化的网络化氧化锌纳米线对二氧化氮、一氧化碳和苯的传感特性进行了研究。在该温度下，铂功能化氧化锌纳米线的传感能力表明它们在化学气体传感器方面具有潜在应用价值。
