摘要: 在本工作中，利用水热法合成了CeO2粉体并探究了其湿敏性能。X射线衍射表明成功得到了结晶度良好的CeO2材料，扫描电镜照片表明所得CeO2呈现纳米块状，长度大约50 nm。交替暴露于11%与97%相对湿度环境中，CeO2纳米块的灵敏度达到281，响应和恢复时间分别为19 s和62 s，显示了全湿度湿敏响应的潜力。
Abstract: In this work, CeO2 powder was synthesized using a hydrothermal method and then its humidity sensing performance was investigated. X-ray diffraction patterns show that CeO2 material with good crystallinity has been successfully obtained, and scanning electron microscopy image indicates that the obtained CeO2 exhibits a nanocube shape with a length of approximately 50 μm. After alternating exposure to 11% and 97% relative humidity, the sensitivity of CeO2 nanocubes reached 281 with response-recovery time of 19 s and 62 s, respectively, indicating the potential for full humidity response.
