通过阳极氧化制成的二氧化钛纳米管对氢高度敏感;例如，在氮气气氛和1000 ppm氢之间循环，对于46 nm直径的纳米管在290 ℃下观察到103的测量电阻变化。氢传感器是完全可逆的，响应时间约为150 s。利用场发射扫描电子显微镜和掠射角X射线衍射（GAXRD）研究了纳米管的表面形貌和晶体结构。(C)2003 Elsevier Science B. V.保留所有权利。
Titanium dioxide nanotubes, made by anodization, are highly sensitive to hydrogen; for example, cycling between nitrogen atmosphere and 1000 ppm hydrogen a variation in measured resistance of 103 is seen for 46 nm diameter nanotubes at 290 degreesC. The hydrogen sensors are completely reversible and have response times of approximately 150 s. Field emission scanning electron microscopy and Glancing angle Xray diffraction (GAXRD) are used to study the surface morphology and crystal structure of the nanotubes. (C) 2003 Elsevier Science B.V.
