采用配位均匀共沉淀法制备了平均粒径约为20nm的Ag/ZnO纳米复合材料。利用XRD、TEM及UV—Vis等技术对样品进行了表征,并将其与用浸渍光分解法和光还原沉积法制备的样品在形貌结构及催化降解甲基橙溶液和工业废水性能方面进行了比较。结果表明,采用配位均匀共沉淀法制备的样品,表现出更加优异的催化降解性能。
The Ag/ZnO nano-composites sized about 20 nm were prepared by using the coordination homogeneous co-precipitation method. XRD, TEM and UV-Vis spectrometry were used to characterize the microstructure and morphology of the products. The impregnation photolysis method and photoreduction method were also used to prepare the Ag/ZnO nano-composites, and their property was compared to that of Ag/ZnO nano-composites made by the coordination homogeneous co-precipitation method. The methyl orange and industry wastewater were used to evaluate the degradation performance of the products. The results showed that the product prepared by the coordination homogeneous co-precipitation method exhibited the best performance.
