摘要: 为了研究Au负载量对TiO2/Au光阳极的光吸收能力的影响，本文采用水热法和柠檬酸钠还原法制备了TiO2/Au材料，通过刮涂法制备光阳极。利用紫外–可见吸收、X射线衍射(XRD)、透射电子显微镜(TEM)等手段对不同Au负载量的TiO2/Au材料和TiO2/Au光阳极进行表征分析。结果表明，Au负载量在1.0 wt%时，TiO2/Au光阳极的光吸收能力最佳；低于1.0 wt%时，Au负载量提高，TiO2/Au光阳极的光吸收能力也随之提高；高于1.0 wt%时，Au负载量提高，TiO2/Au光阳极的光吸收能力随之降低。
Abstract: In this paper, in order to investigate the effect of Au loading on the light absorption ability of TiO2/Au photoanode, TiO2/Au materials were prepared by hydrothermal method and sodium citrate reduction method, and photoanode was prepared by scratch coating method. Characterization and analysis of TiO2/Au materials and TiO2/Au photoanodes with different Au loadings were carried out using UV-visible absorption, X-ray diffraction (XRD), transmission electron microscopy (TEM), and other methods. The results showed that the TiO2/Au photoanode had the best light absorption capacity when the Au loading was 1.0 wt%; when the Au loading was below 1.0 wt%, the light absorption capacity of TiO2/Au photoanode also increased with the increase of Au loading; when the Au loading exceeded 1.0 wt%, the light absorption capacity of TiO2/Au photoanode decreased as the Au loading increased.
