摘要

采用低温水热合成法合成了金红石型TiO2纳米棒。通过引入低带隙半导体材料，如CdS、CdSe和CdS/CdSe，实现了TiO2纳米棒在可见光范围内的活性，并对其光电化学性能进行了比较研究。形态、微观结构和光催化表征结果表明，与其他光电极相比，TiO2/CdS/CdSe复合光电极表现出优异的光催化性能，这是由于单晶TiO2核心组分以及敏化的CdSe/CdSe纳米颗粒的良好能带排列。

Design and Development of Novel Nanostructured Visible-Light Active Photoelectrodes based on TiO2 Nanorods for Solar Hydrogen Generation

Single crystalline rutile TiO₂ nanorods were synthesized by using low temperature hydrothermal synthesis method. Activity of the TiO₂ nanorods in the visible light range was achieved by introducing low bandgap semiconductor materials, such as CdS, CdSe, and CdS/CdSe and their photoelectrochemical performances were comparatively investigated. Morphological, microstructural and photocatalytic characterization results revealed that TiO₂/CdS/CdSe composite photoelectrode demonstrated superior photocatalytic performance compared to others owing to single crystalline TiO₂ core component as well as favorable band alignment of the sensitized CdSe/CdSe nanoparticles.
