【摘要】 以Zn(NO3)2、尿素和200目酸洗白云母粉为原料,采用化学沉淀法制得纳米ZnO/白云母复合材料。对合成产物进行了表征,研究了它在UV下的光催化降解的性质。结果表明:ZnO与白云母复合程度良好,沉积在白云母表面的纳米ZnO平均粒径约24.46nm。该复合材料可在光催化的条件下降解有机染料,在距液面高50cm的30W紫外线灯的照射下,对有机物的脱色速率常数是0.11/h。此类产品在化妆品、涂料、环保等方面的应用将具有较高的经济价值。更多还原

【Abstract】 This research used homogeneous sedimentation method to synthesis nano-ZnO /muscovite composite with Zn(NO3)2, urea and muscovite powder. Meanwhile, synthetic product was characterized. Furthermore, UV-vis was also used to research the character of photochemical catalysis degradation of nano-ZnO/muscovite composites. The results indicated that, the compound degree between ZnO and muscovite was good, nano-ZnO particles deposited on the surface of muscovite with average grain diameter 24.46nm. This kind of composite materials could degrade the organic dye with the condition of photochemical catalysis, under the illumination of 30W ultraviolet lamp, which aparted above liquid level 50cm, the degradation rate of compounds attained 0.11/h. The application of this kind of product in cosmetics, coating, environmental protection and so on will have higher economic value.更多还原
