二氧化钛薄膜和厚膜促进与铂和有机敏化剂，包括新的二萘嵌苯二酰亚胺染料（PDI）的制备和测试的二氧化碳减少与水在可见光下。采用溶胶-凝胶法制备了TiO 2薄膜。通过湿浸渍将Pt结合在TiO 2表面[Pt（on）.TiO2]，或者通过在溶胶中添加前体将Pt结合在TiO 2膜[Pt（in）.TiO2]中。当三（2，2 '-联吡啶）钌（II）氯化物六水合物用作敏化剂时，除了对甲烷产生的可见光活性之外，还观察到H-2释放。本研究中使用的二萘嵌苯二酰亚胺衍生物显示出与三（2，2 '-联吡啶基）氯化钌（II）六水合物类似的光捕获能力。
TiO2 thin and thick films promoted with platinum and organic sensitizers including novel perylene diimide dyes (PDI) were prepared and tested for carbon dioxide reduction with water under visible light. TiO2 films were prepared by a dip coating sol-gel technique. Pt was incorporated on TiO2 surface by wet impregnation [Pt(on).TiO2], or in the TiO2 film [Pt(in).TiO2] by adding the precursor in the sol. When tris (2,2'-bipyridyl) ruthenium(II) chloride hexahydrate was used as sensitizer, in addition to visible light activity towards methane production, H-2 evolution was also observed. Perylene diimide derivatives used in this study have shown light harvesting capability similar to the tris (2,2'-bipyridyl) ruthenium(II) chloride hexahydrate.
