在甲酰胺+甘油(体积比1:1)+1wt%NH4F+1wt%H2O的混合溶液中,以直径1mm的锆丝为阳极,以石墨筒为对电极,采用阳极氧化法在锆丝表面制备出长度约30μm、管径120~150nm的氧化锆纳米管阵列。通过扫描电镜、透射电镜和X射线衍射仪对氧化物的形貌、组成和物相结构进行了表征。分别以铂片和石墨棒作对电极的实验表明,对电极的形状对纳米管阵列的形成有显著影响。对氧化锆纳米管阵列的形成机理进行了初步探讨。
In a mixed solution of formamide + glycerol (volume ratio of 1: 1) + 1wt% NH4F + 1wt% H2O, using a zirconium wire 1mm in diameter as an anode and a graphite cylinder as a counter electrode, anodization was performed on the zirconium wire surface A length of about 30μm, diameter 120 ~ 150nm zirconia nanotube array. The morphology, composition and phase structure of the oxide were characterized by scanning electron microscopy, transmission electron microscopy and X-ray diffraction. Experiments with platinum plates and graphite rods as the counter electrode respectively show that the shape of the counter electrode has a significant effect on the formation of the nanotube array. The formation mechanism of zirconia nanotube arrays was discussed.
