摘要
用低温水热法(60℃)在纯水中在锌片上制备了ZnO纳米锥丛林阵列,并使用扫描电子显微镜、X射线衍射仪和能谱仪等手段对其形貌、结构和化学成分进行了表征。结果表明,锌片表面被成簇的ZnO纳米锥和独立生长的ZnO纳米锥完全覆盖,ZnO纳米结构的纯度较高晶体质量也较好。ZnO纳米锥丛林阵列对甲基橙和亚甲基蓝都具有良好的催化性能,证明ZnO纳米锥丛林阵列对染料具有普遍催化作用。还分析了ZnO纳米锥丛林阵列的生长机制和光催化机理。
Nanocone arrays of ZnO were synthesized on Zn foil via a simple low temperature(60 OC)hydrothermal route. The morphology, structure and composition of the prepared nanocone arrays were characterized by means of scanning electron microscopy, X-ray diffractometer and energy disperse spectroscopy. Results show that the surface of Zn-substrate was fully covered by clustered ZnO-nanocones and standalone ZnO-nanocones, the nanocone arrays of ZnO are of high purity and high degree of crystallinity. The prepared nanocone arrays of ZnO exhibit good photocatalytic performance for aqueous solutions of methyl orange and methylene blue, indicating that the nanocone arrays of ZnO may be a general purpose photocatalyst for the degradation of different dyes. Furthermore, the possible growth and photocatalytic mechanisms of the nanocone arrays of ZnO were also analyzed.
