氧化石墨烯复合钨钼酸铋的合成与光催性能初探

Preparation of Bismuth Tungstate and Graphene Oxide Composite and Its Photocatalytic Activity

采用改进Hummers法制得氧化石墨烯、再用水热法制备氧化石墨烯钨钼酸铋复合材料,产物煅烧处理后用多种手段进行表征。研究了复合材料对亚甲基蓝的光催降解情况。结果显示,复合光催化剂有完整的球形结构,降解效果良好,当氧化石墨烯的用量为3%、作用90min,降解可达90%以上。

The experiment adopted the improved Hummers method to prepare Graphene Oxide(GO).Then,the composite was obtained by hydrothermal method and was characterized by SEM,XRD and IR.Preliminary study of the adsorption-degradation properties of Methylene blue by the product were carried out.Results showed that the composite posses a spherical structure.When the amount of GO reached 3%,the degradation could exceed 90% after 90 minutes' reaction.
