Abstract
采用水热合成技术, 以盐酸、去离子水和钛酸丁酯为反应前驱物, 在透明导电玻璃(FTO)衬底上合成TiO 2 纳米线束阵列. 采用X射线衍射(XRD)、扫描电子显微镜(SEM)和高分辨透射电镜(TEM)对其结构和形貌进行了分析. 结果表明: 在FTO衬底上形成了垂直排列的具有金红石结构的单晶TiO 2 纳米线束阵列, TiO 2 纳米线束由直径4~6nm的几十条纳米线聚集在一起, 形成宽度约110~210nm、长度约3?m的四方柱状结构. 研究了以TiO 2 纳米线束阵列为光阳极制备的染料敏化太阳能电池的光电性能, 其开路电压为0.72V, 短路电流密度为2.9mA/cm 2 , 填充因子为0.42, 转换效率为0.88%.
