摘　　要：本论文将蓝靛果花青素(主要成分为矢车菊素3-O-葡萄糖苷,简称C3G)引入到TiO_(2)薄膜体系中,采用交替沉积自组装法成功制备了C3G/TiO_(2)复合膜电极并对其进行表征,通过光电流-时间曲线和光电流-光电压曲线等测试考察了复合膜电极的光电性能。实验结果表明,C3G/TiO_(2)复合膜电极的光电流响应较单纯的TiO_(2)膜电极明显提高,其光电转换效率比单纯的TiO_(2)膜电极提高了80%。同时,C3G/TiO_(2)复合膜电极还展现出对甲醇更好的光电催化氧化活性。In this paper,indigo anthocyanins(the main component is cyanidin 3-O-glucoside,ref.C3G)were introduced into the TiO_(2) film system.C3G/TiO_(2) composite film electrodes were successfully prepared by LbL self-assembly.We used the photocurrent-time curve and the photocurrent-photovoltage curve to investigate the photoelectric performance of the composite film electrodes.The experimental results show that the photocurrent response of the C3G/TiO_(2) composite film electrode is significantly higher than that of a simple TiO_(2) film electrode,and its photoelectric conversion efficiency is 80%higher than that of a simple TiO_(2) film electrode.At the same time,the C3G/TiO_(2)composite film electrode also showed better photocatalytic oxidation activity for methanol.
