摘要
采用阳极氧化法,以锌片为阳极,石墨板为阴极,水/无水乙醇(体积比1∶1)+1.2%氯化铵+不同体积30%双氧水的混合溶液作为电解液,制备了片状纳米ZnO,并利用冷场扫描电镜、X射线衍射和傅里叶红外光谱对试样的形貌、物相和结构进行表征。在紫外灯照射下对10mg/L的苯酚溶液进行光催化降解,考察了片状纳米ZnO的光催化活性。结果表明:当双氧水体积为0.4mL时,可以得到高结晶度、高纯度的片状纳米ZnO,且对苯酚的降解率高达96.37%。
Nano flake zinc oxide was prepared by anodizing Zn sheet in the electrolyte composed of wa- ter ＋ ethanol（volume ratio 1 ： 1）, 1.2%NH4C1 and different volume of 30% hydrogen peroxide. The product was characterized by cold field emission scanning electron microscope （FE-SEM）, X-ray dif- fraction （XRD） and Fourier Transform Infrared Spectroscopy. The photocatalytic activity of nano flake zinc oxide was evaluated by the photocatalytic degradation of phenol under UV light irradiation. Results show that nano flake zinc oxide with high crystallinity, high purity can be obtained when hy- drogen peroxide volume is 0.4 mL.and the phenol degradation rate can be up to 96.37%.
