【摘要】 用光电化学方法和UV-vis吸收光谱研究了PbS和RuL₂（NCS）₂（L=2,2’-bipydine-4,4’-dicarboxylic acid）复合敏化SnO₂纳米晶多孔膜电极的光电化学行为.实验表明,复合敏化比用PbS或RuL₂（NCS）₂分别单独敏化的效果好,不仅使电极的光吸收拓展到可见光区,而且复合敏化显著提高了光电转换效率,并讨论了复合敏化电极的电荷传输机理.更多还原

【Abstract】 The photoelectrochemical behavior of SnO2 nanoporous film electrode sensitized from composite PbS/RuL2 ( NCS )2 was investigated by photoelectrochemical methods and UV - vis absorption spectroscopy. The results showed that the photosensitization of composite PbS and RuL2(NCS)2 for SnO2 nanoporous film electrode largely improved the conversion efficiency of light to electricity and was superior to the photosensitization of PbS or of RuL2(NCS)2 respectively. The charge transfer mechanism of compositely sensitized electrode was discussed in detail.更多还原
