With the aim of developing new energy resources, construction of an artificial photosynthetic system which produces fuels from sunshine and water has been investigated. By utilizing electrode-coated polymer membranes containing dispersed functional molecules, water oxidation catalyst, carbon dioxide reduction catalyst, and proton reduction catalyst have been studied.As for the water oxidation catalyst, it has been found that ammine-coordinated trinuclear Ru complex (Ru-red) shows high activity when adsorbed into platinum black. Its activity. could successfully be analyzed based on distribution of the molecule-to-molecule distance of the dispersed complex. By using this catalyst system coupled with a Nafion membrane containing dispersed sensitizer, Ru (bpy) 32+, and by designing a bilayr system, it was succeeded to construct a photoelectrochemical water oxidation system to evolve dioxygen.For C02 reduction, cobalt-phthalocyanine (CoPc) has been found to have a high catalytic activity. The activity of its derivatives has been studied, and a new reaction mechanism proposed which involves third electron injection to the complex catalyst.

为了开发新的能源资源，已经研究了通过阳光和水产生燃料的人工光合系统的建设。 By utilizing electrode-coated polymer membranes containing dispersed functional molecules, water oxidation catalyst, carbon dioxide reduction catalyst, and proton reduction catalyst have been studied.As for the water oxidation catalyst, it has been found that ammine-coordinated trinuclear Ru complex (Ru-red) shows high activity when adsorbed into platinum black.它的活动。可以基于分散复合物的分子到全分子距离的分布成功分析。通过使用该催化剂系统，再加上含有分散敏化剂RU（BPY）32+的Nafion膜，并通过设计Bilayr系统，成功地构建了一个光电油化学水氧化系统以进化二氧化型。已经研究了其衍生物的活性，并提出了一种新的反应机制，涉及对复杂催化剂的第三电子注射。
