以棉花为模板制备了ZnSnO3中空纤维。棉纤维渗透与硝酸锌和氯化锡溶液，随后在空气中在高温下烧结，以产生最终的ZnSnO3中空纤维。通过X射线衍射和扫描电子显微镜对样品的结构和形貌进行了进一步的分析。结果表明，所制备的中空纤维均为正交晶结构，结晶度较高，由大量的ZnSnO3纳米棒组成。在此基础上，制备了气敏元件，并对乙醇气敏特性进行了研究。该传感器对乙醇具有高灵敏度，响应速度快，选择性好，稳定性好，在环境、食品、驾驶员饮酒等方面具有潜在的应用前景。
Biomorphic ZnSnO3hollow fibers have been fabricated using cotton as biotemplates. Cotton fibers are infiltrated with zinc nitrate and stannic chloride solution and subsequently sintered in air at high temperatures to produce the final ZnSnO3hollow fibers. The samples have further distinctions in structure and morphology by X-ray diffraction and scanning electron microscopy. It showed that all the samples present an orthorhombic structure of high crystallinity, and the hollow fibers were composed of numerous ZnSnO3nanorods. Furthermore, gas sensors were fabricated and an investigation of ethanol sensing properties has been conducted. The sensor, based on ZnSnO3hollow fibers calcined at 500 °C, shows highly sensitive to ethanol with fast response, good selectivity and stability, indicating its potential applications for environment and food or the drinking status of drivers.
