摘要

摘要对纳米材料形态的控制进行了研究，以用于所需的应用。1D纳米材料由于其优异的载流子迁移性和巨大的比表面积而非常适合各种应用。由于它们的优势，人们开发了各种方法来朝着特定的方向发展。在此，我们介绍了一种使用水溶液在没有种子或基底的情况下合成作为1D材料的独立式水合氟化锌（ZnOHF）纳米带的简单方法。使用氟化锌和六亚甲基四胺（HMT）在80°C下合成ZnOHF纳米带3小时。即使合成温度较低，ZnOHF也表现出良好的结晶度和均匀的纳米带结构。ZnOHF纳米带沿宽度小于100nm的方向生长了几微米。此外，纳米带的生长方向由HMT的浓度控制。纳米带的宽度随着HMT浓度的降低而变宽。认为HMT分解产生的OH−和NH4+离子可能影响ZnOHF的晶体成核和生长。图形摘要

Facile synthesis of zinc hydroxyfluoride nanobelt and effect of hexamethylenetetramine for growth direction

ABSTRACT Control of nanomaterial morphology has been investigated to utilize for the desired application. 1D nanomaterials are ideal for various applications because of their excellent carrier transportability and huge specific surface area. Due to their advantages, various methods have been developed to grow in a specific direction. Herein, we introduced a simple synthesis method of freestanding Zinc hydroxidefluoride (ZnOHF) nanobelt as 1D material without seed or substrate using aqueous solutions. The ZnOHF nanobelt was synthesized using zinc fluoride and hexamethylenetetramine (HMT) at 80°C for 3 h. Even though low synthesis temperature, ZnOHF demonstrated good crystallinity and a homogeneous nanobelt structure. The ZnOHF nanobelts were grown over several μm to <010> direction with less than 100 nm width. In addition, the growth direction of the nanobelt was controlled by the concentration of HMT. The width of the nanobelt was broader by a decrease in HMT concentration. It was considered that crystal nucleation and growth of ZnOHF could be influenced by OH− and NH4 + ions generated from HMT decomposition. GRAPHICAL ABSTRACT
