摘　　要：通过溶剂热合成法合成ZnO微纳米颗粒,将Zn(CH_(3)COO)_(2)·2H_(2)O作为锌源,将C_(19)H_(42)BrN作为分散剂,用去离子水和定量的C_(2)H_(5)OH作为溶剂,和适量的氨水装入高压反应釜中高温高压下孵化制得微纳米ZnO。使用XRD表征晶体结构确定为目标产物,再使用电镜测得不同反应条件下的样品的形状,探究不同反应温度和反应时间下制得的ZnO微纳米颗粒的光催化性能。以亚甲基蓝溶液作为被有机物污染的废水,在紫外光源下测试加入ZnO微纳米颗粒的亚甲基蓝溶液(MB)的吸光度变化。实验结果表明:该方法制备的ZnO确实为微纳米级别,且形貌多样,光降解效率良好,150分钟对亚甲基蓝的降解率是95.45%。ZnO micro-nano particles are synthesized by solvothermal synthesis.Zn(CH_(3)COO)_(2)·2H_(2)O is used as the zinc source,C_(19)H_(42)BrN is used as the dispersant,deionized water and a certain amount of C_(2)H_(5)OH are used as the solvent,and an appropriate amount of ammonia is put into a high-pressure reactor under high temperature and high pressure to obtain micro-nano ZnO.The crystal structure is characterized by XRD and determined as the target product.The shape of samples under different reaction conditions is measured by electron microscope.The photocatalytic properties of the prepared ZnO micro-nano particles under different reaction temperature and time are investigated.Taking methylene blue solution as the wastewater polluted by organic matter,the absorbance change of methylene blue solution added with ZnO micro-nano particles is tested under the ultraviolet light source.The experimental results show that the prepared ZnO by this method is indeed micro-nano level,with diverse morphology and good photodegradation efficiency.The degradation rate of methylene blue is 95.45%in 150 minutes.
