采用两步溶液法在Al 2 O3管上直接合成了定向氧化锌纳米棒，并通过X射线衍射（XRD）和扫描电子显微镜（SEM）对其进行了表征。所制备的氧化锌纳米棒直径为10- 30 nm，长度约为1.4 μ m，分布均匀。对100 pp甲醇和氢气的响应S-r（=R-a/R-g）分别达到18.29和10.41，比文献报道的值提高了一倍，表明了开发稳定、灵敏的气体传感器的潜力。(C)2007 Elsevier B. V.保留所有权利。
Aligned zinc oxide nanorods were synthesized directly via a two-step solution approach on an Al2O3 tube, and were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The zinc oxide nanorods prepared were uniform with diameters of 10-30nm and lengths about 1.4 mu m. The response S-r (=R-a/R-g) of the alignedzinc oxide nanorod sensorreached 18.29 and 10.41 to 100pp methanol and hydrogen, respectively, which was a two-fold increase compared with that reported in literature, demonstrating the potential for developing stable and sensitive gas sensors.
