| 中文摘要: |
| 采用胶体晶体模板技术和磁控溅射工艺，制备了银反点阵列修饰TiO2薄膜。用扫描电子显微镜、X射线衍射、紫外-可见分光光度计和四探针测试仪等手段对复合薄膜的结构和光催化性能进行了表征。结果表明，银反点阵列具有优良的导电性能，可有效抑制光生载流子的复合，增强载流子输运的效率，使TiO2的光催化性大幅提升。 |
| 英文摘要: |
| Ag antidot arrays modified TiO2 films are obtained by PS colloidal crystal templates technique and magnetron sputtering method. And then, the microstructure and the photocatalysis performance of the samples are characterized by using scanning electron microscopy (SEM), x-ray diffraction (XRD), UV-Vis spectrophotometer, and four-point probe. The experimental results showed that Ag antidot arrays possess excellent electrical conductivity and could effectively promote the separation of surface photoinduced charge carrier of TiO2 nanoparticles, which is responsible for the remarkable increase in photocatalytic activity. |
