采用表面活性剂辅助水热法一锅法合成了具有高光催化活性的Ag-TiO 2复合中空结构。TEM测试表明，样品由空心球及其管状聚集体组成。表面活性剂十六烷基三甲基溴化铵（CTAB）在Ag-TiO 2中空结构的构建中起着关键作用。Ag-TiO 2中空结构对橙子的降解具有良好的光催化活性。
This paper describes a one-pot surfactant-assisted hydrothermal method for the synthesis of Ag-TiO2composite hollow structures with high photocatalytic activity. TEM measurement reveals that the sample is composed of hollow spheres and their tube-like aggregates. The surfactant cetyltrimethylammonium bromide (CTAB) plays a key role in the construction of the Ag-TiO2hollow structures. The Ag-TiO2hollow structures showed effective photocatalytic activity for the decomposition of methyl orange.
