摘要
用溶剂热法制备了Ag/ZnO纳米复合材料,用扫描电子显微镜(SEM)、透射电子显微镜(TEM)、能量色散谱点(EDS)分析了复合材料的表面形貌及结构。以亚甲基蓝为模拟污染物,在紫外光照射下考察了纳米Ag/ZnO复合材料的光催化活性。结果表明,一定量银沉积能有效地改善ZnO对亚甲基蓝的光催化降解性能。
Silver-modified ZnO composites were prepared by solvothermal reaction.Scanning electron microscopy（SEM）,transmission electron microscopy（TEM）,energy diopersive spectrometer（EDS） were used to investigate the morphology and structure.The photocatalytic activity of the composites was tested using methylene blue as the model reaction under the irradiation of ultraviolet light.The results indicate that the nano-Ag/ZnO composites exhibits a higher photocatalytic activity toward the degradation of methylene blue.
