摘要
用光电化学方法研究了Cds、Pbs和RuL2（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rul（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．
Photosensitization by composite sulfides and Ru(Ⅱ) complex for TiO2 nanoporousfilm was investigated with photoelectrochemical methods. The results showed that the conversionefficiency of light to electricity was greatly improved. This could be explained that in the case ofthis type of photosensitization, the back electron transfer from the TiO2 conduction band to thesolution was refrained, thus the loss of electrons was avoided.
