Effect of Fluoride Content on Morphology and Phase Composition of ZrO2 Nanotubes
Source abstract
Abstract
采用阳极氧化法在丙三醇+NH 4 F+5vol% H 2 O的电解液中制备了高度有序的ZrO 2 纳米管阵列, 详细考察了溶液中F含量(0.1~1.1 mol/L)对纳米管形貌﹑相结构和化学组成的影响. 利用扫描电子显微镜(SEM), X射线衍射仪(XRD)和X射线光电子能谱仪(XPS)对不同条件下制备的管径约90~130 nm, 管长约4.8~9.1 μm的纳米管形貌和结构进行了表征. 结果显示, 在含有0.7 mol/L NH4F的电解液中获得了高度有序且垂直导向的四方相ZrO2纳米管阵列, 而在较低浓度的电解液中制备的纳米管阵列为无定形结构, 较高浓度下纳米管阵列出现坍塌. 此外, 纳米管近表层处F/O原子比也随F-浓度的变化而变化.
