| 摘 要： | 用光电化学方法研究了ＣｄＳ,ＰｄＳ和Ｒ１１Ｌ２（ＮＣＳ）２,（Ｌ＝２,２′－ｂｉｐｙｄｉｎｅ－４,４′－ｄｉｃａｒｂｏｘｙｌｉｃａｃｉｄ）复合敏化ＴｉＯ２纳米晶电极的光电化学行为,结果表明,采用复合敏化比用Ｒ１１（ＩＩ）络合物单独敏化ＴｉＯ２纳米晶电极效果好,大大提高了光电转换效率,主要原因是采用复合敏化,可防止ＴｉＯ２导带上由光注入产生的电子的反向转移,避免了电子的损失。

| Abstract: | Photosensitization by composite sulfides and Ru(Ⅱ) complex for TiO2 nanoporous film was investigated with photoelectrochemical methods. The results showed that the conversion efficiency of light to electricity was greatly improved. This could be explained that in the case of this type of photosensitization, the back electron transfer from the TiO2 conduction band to the solution was refrained, thus the loss of electrons was avoided. |
