One-dimensional, hollow nanostructured materials are among the most promising materials for sensing applications owing to their high surface area that facilitates the adsorption of target gases. Accordingly, for gas sensing studies, hollow ZnO nanowires (NWs) with different surface areas were successfully synthesized herein by using polycarbonate membranes with different pore sizes as templates, and deposition of ZnO via the atomic layer deposition technique. The sensing properties of the synthesized hollow ZnO NWs were examined for CO and NO, revealing their comparative sensing performances with ZnO nanomaterials-based sensors reported in literature. This study highlights a novel way of synthesizing hollow ZnO NWs by using membrane template and their promising sensing properties as well.
一维空心纳米结构材料因其高表面积有利于目标气体的吸附，是传感应用中最具前景的材料之一。因此，在本研究中，通过使用不同孔径的聚碳酸酯膜作为模板，并采用原子层沉积技术沉积氧化锌，成功合成了具有不同表面积的空心氧化锌纳米线（NWs）用于气体传感研究。对合成的空心氧化锌纳米线对一氧化碳和一氧化氮的传感性能进行了检测，揭示了它们与文献报道的基于氧化锌纳米材料的传感器相比的传感性能。本研究突出了一种利用膜模板合成空心氧化锌纳米线的新方法及其良好的传感性能。
