| 目的 研究光电功能涂层制备方法对粉末薄膜光电极的光电转换效率的影响。方法 采用喷涂法制备光电材料的FTO薄膜光电极，观察其表面形貌，通过研究光电流和光电位的变化评价光电材料的光电转换效率，并与点涂法和电泳法制备的光电极进行对比分析。结果 喷涂法制备的二氧化钛FTO薄膜光电极性能优于其他两种方法制备的电极，在3.5%氯化钠溶液中，光电位变化更稳定，压降大于500 mV，光电流变化大于60 μA/cm2。结论 喷涂法制备光电极能够提高半导体粉末材料的光电化学效率，是一种可推行的薄膜光电极制备方法。 |

| Objective To study influences of preparation method of photoelectric functional coating on photoelectric conversion efficiency of TiO2 thin films. Methods The FTO thin film photoelectrodes were prepared by spraying. Based on observation of surface appearance, the photoelectric conversion efficiency of photoelectric materials was estimated by studying changes of light current and photopotential and compared with photoelectrode prepared by spot coating and electrophoresis. Results The TiO2 FTO thin-film prepared by spraying has better performance than electrode prepared with the other two methods. In 3.5% NaClsolution, the photoelectricity change was more stable, the pressure drop was larger than 500 mV and the light current changed by more than 60 μA/cm2. Conclusion Preparing photoelectrode by spraying could improve the photoelectrochemical efficiency of the semiconductor powder material. It is a thin film photoelectrode preparation method which could be practiced. |
