PbS/Ru(Ⅱ)配合物敏化Cd(Ⅱ)掺杂TiO2纳米晶电极的光电化学
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380~600 nm范围内,PbS/RuL2(NCS)2复合敏化Cd掺杂电极的效果比PbS和RuL2(NCS)2单独敏化的效果更好.

Photoelectrochemical Study of PbS/RuL2(NCS)2 Sensitized Cd(Ⅱ)Doped Nanoporous TiO2 Film Electdode
Abstract:
5%Cd (Ⅱ)doped nanoporous TiO2 film electrode was prepared.The photoelectrochemical behavior of the electrodes sensitized by PbS, RuL2(NCS)2(L=2, 2'-bipy ridine-4, 4-dicarboxy lic acid)and composite PbS /RuL2(NCS)2 respectively have been investigated.The results showed that the photocurrent generations of the sensitized Cd (Ⅱ)doped TiO2 film electrodes ex tended to visible and infrared regions and the electrode sensitized by composite PbS/RuL2 (NCS)2 was much better than others in solar energy conversion.
