摘要
合成了Ｃｄ（Ⅱ）掺杂ＴｉＯ２纳米粒子（掺杂５％Ｃｄ（Ⅱ）），用光电化学方法测定了ＰｂＳ、ＲｕＬ２（ＮＣＳ）２（Ｌ＝２，２′联吡啶４，４′二羧酸）分别敏化及ＰｂＳ／ＲｕＬ２（ＮＣＳ）２复合敏化该纳米晶膜电极的光电化学行为，实验证明，ＰｂＳ、ＲｕＬ２（ＮＣＳ）２单独敏化和ＰｂＳ／ＲｕＬ２（ＮＣＳ）２复合敏化的Ｃｄ掺杂电极比纯的ＴｉＯ２电极的光电流产生的起始波长都向长波方向移动；在３８０～６００ｎｍ范围内。
Cd(Ⅱ) doped nanoporous TiO 2 film electrode was prepared. The photoelectrochemical behavior of the electrodes sensitized by PbS, RuL 2(NCS) 2(L=2,2′ bipyridine 4,4 dicarboxylic acid) and composite PbS/RuL 2(NCS) 2 respectively have been investigated. The results showed that the photocurrent generations of the sensitized Cd(Ⅱ) doped TiO 2 film electrodes extended to visible and infrared regions and the electrode sensitized by composite PbS/RuL 2(NCS) 2 was much better than others in solar energy conversion.
