通过将Ag(2)O纳米粒子与TiO(2)纳米带进行简单的物理混合，合成了静电自组装Ag(2)O/TiO(2)纳米带异质结构。采用高分辨透射电镜对Ag(2)O/TiO(2)纳米带异质结构的形貌和微观结构进行了表征。界面主导的高紫外光催化活性和光致发光强度下降的复合催化剂证实了Ag(2)O纳米颗粒与TiO(2)纳米带之间的异质结构效应。x射线光电子能谱提供了它们之间异质结构上电荷转移的直接证据。
Electrostatic self-assembled Ag(2)O/TiO(2) nanobelts heterostructure was synthesized via simple physical mixing of Ag(2)O nanoparticles and TiO(2) nanobelts. The morphologies and microstructures of Ag(2)O/TiO(2) nanobelt heterostructure were characterized by high resolution transmission electron microscopy. The interface dominated high UV photocatalytic activity and degraded photoluminescence strength of composite catalyst confirmed the heterostructure effect between Ag(2)O nanoparticles and TiO(2) nanobelts. X-ray photoelectron spectroscope provided direct evidence of charge transfer on the heterostructures between them.
