摘　　要：以阳离子交换树脂为载体，经吸附、光还原制备了纳米Ag／树脂复合物，采用扫描电镜、X射线能量散射谱、X射线光电子能谱等手段对其进行了表征。结果表明：所制备的Ag／树脂复合物粒径在300～600 gm之间，阳离子树脂表面由10-80 nm的纳米银晶粒组成。分别在紫外光和可见光下，研究了Ag／树脂复合物对甲基橙溶液的光催化降解效果，结果表明：Ag／树脂复合物具有很好的光催化性能。The Ag/resin composite was prepared by ion exchange and photoreduction with cation resin as a template. The samples werecharacterized by SEM, EDS and XPS. The result indicates that the diameter of the Ag/resin composite is 300-600 ~tm, and the size of thesilver nanocrystals on the cationic resin is between 10-80 nm. Irradiations were performed with UV light and the sunlight, and methylorange solution was used as object, and the photocatalytic activity of Ag/resin composite was studied. The results show that the Ag/resincomposite has good photocatalytic activity.
