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.

以开发新能源为目的，研究了利用太阳光和水生产燃料的人工光合系统的构建。利用分散有功能性分子的电极涂敷型高分子膜，研究了水氧化催化剂、二氧化碳还原催化剂、质子还原催化剂等，发现在水氧化催化剂中，氨配位的三核钌络合物（Ru-red）吸附在铂黑中时，显示出高活性。它的活动。可以成功地分析基于分散的络合物的分子到分子距离的分布。将该催化体系与含有分散敏化剂Ru（bpy）32+的Nafion膜耦合，通过设计双层体系，成功构建了光电化学水氧化体系，并对CO2还原反应进行了研究，发现酞菁钴（CoPc）具有很高的催化活性.研究了其衍生物的催化活性，提出了一种新的反应机理，即第三次电子注入络合催化剂。
