中文摘要：

通过XRD、TEM测试研究了自制ZnO／Ag纳米复合材料的结构和形貌，通过UV检测确定了以该纳米复合材料为光催化剂，在不同条件下对甲基橙的光催化降解率。结果表明：与空气煅烧相比，真空煅烧所得纳米复合材料的光催化降解效果更好，且光催化降解率随纳米复合材料用量增加而增大：甲基橙溶液的pH在5左右时，光催化降解率最高：H2O2浓度为0．9g／L时，光催化降解率可达100％。

英文摘要：

The homemade ZnO/Ag nanocomposite materials were characterized by XRD and TEM. Using nanocomposite materials as photocatalysis, the degradation rate of the methyl-orange in different condition were studied by UV. The results show that： the nanocomposite materials sintered in the vacuum is better than that in the atmosphere, and the photocatalytic degradation rate of methyl orange would increases with the weight rise of ZnO/Ag nanocomposite materials. The suitable condition ofpH is the weak acid; when pH value is about 5, the effect of the photocatalytic degradation is the best. When the concenstration of H2O2 is 0.9 g/L, the photocatalytic degradation rate is 100%.
