Abstract TiO2/PbS heterojunction with Au doped photoelectrode was fabricated by simple hydrothermal, Chemical bath deposition (CBD) and successive ionic layer adsorption and reaction (SILAR) methods. The photoelectrochemical (PEC) characterizations showed the TiO2/PbS heterojunction with Au doped photoanodes had better PEC performance than TiO2 and certain photoelectrocatalytic degradation ability of RhB. The photocurrent density achieved 4.753 mA/cm2 and the degradation efficiency of RhB could be degraded to 47.4%. The improvement of properties was due to the formation of heterojunction and doped element facilitated the separation and mobility of the photoinduced electrons and holes in photoanode. The photoelectrode may be a good candidate for photoelectrocatalytic degradation.

用于光电催化降解的 Au 掺杂 TiO2/PbS 异质结的简便合成

摘要 通过简单的水热法、化学浴沉积法（CBD）和连续离子层吸附反应（SILAR）法制备了具有金掺杂光电极的TiO2/PbS异质结。光电化学(PEC)表征表明，掺杂Au光阳极的TiO2/PbS异质结比TiO2具有更好的PEC性能和一定的RhB光电催化降解能力。光电流密度达到 4.753 mA/cm2，RhB 的降解效率可降低至 47.4%。性能的改善是由于异质结的形成和掺杂元素促进了光阳极中光生电子和空穴的分离和迁移。光电极可能是光电催化降解的良好候选者。
