| 摘 要： | 采用简单的溶剂热法制备了ZnO纳米花状枝晶,枝晶主干长约400～500 nm,晶枝长约500～700 nm.利用XRD、SEM及EDS测试手段对ZnO纳米花进行物相、结构、形貌和成分表征的结果显示,ZnO纳米花为六方相纤锌矿结构,其中有少量钴的掺杂.所制备的ZnO纳米花对甲基橙溶液具有很好的光催化性能,在1.5 h光催化实验后,其降解率达到91.1%.

| Abstract: | Nanoflower-like ZnO branched crystals with the branch length of 500~700 nm and the trunk length of 400~500 nm were prepared by a simple solvothermal method.The phase,morphology and structure of as-prepared ZnO nanoflowers were characterized by XRD,SEM and EDS techniques,showing a hexagonal Co-dopped wurtzite structure.ZnO nanoflowers showed excellent photocatalytic activity of methyl orange,with a degeneration rate of 91.1% after 1.5-hour experiment. |
