In this study, several novel photosensitizers have been synthesized, and TiO_2 photoelectrodes sensitized by these novel sensitizers have been prepared to achieve an efficient solar-water-splitting system. Novel ruthenium photosensitizers having a natural dye as a ligand, or having an ortho-dicarboxyphenyl group as an anchoring unit have been successfully synthesized. In addition, the adsorption behavior of these photosensitizers for the TiO_2 surface has been investigated in detail, and the optimized conditions to prepare efficient dye-sensitized TiO_2 photoelectrodes have been decided.

本研究合成了几种新型光敏剂，并制备了这些新型光敏剂敏化的TiO_2光电极，以实现高效的太阳能分解水系统。已经成功合成了具有天然染料作为配体或具有邻二羧基苯基作为锚定单元的新型钌光敏剂。此外，还详细研究了这些光敏剂在TiO_2表面的吸附行为，并确定了制备高效染料敏化TiO_2光电极的优化条件。
