在水溶液中，三(2，2‘-联吡啶)Ru(II)光敏电子从EDTA转移到甲基紫精，紫精的还原形式被用来将水还原为H_2。H2的生成速率取决于光照强度、溶液的pH值、用于水还原步骤的催化剂的类型和浓度以及生色团、EDTA和甲基紫精的浓度。对这些因素进行了优化以生产氢气，并尝试了其他类型的紫精，但没有一种比甲基紫精更好。简要描述了这些发现对水循环裂解成H_2和O_2的意义。
Tris(2,2′-bipyridyl)ruthenium(II) photosensitised electron transfer from EDTA to methyl viologen in aqueous solution and the reduced form of the viologen was used to reduce water to H2. The rate of formation of H2 was dependent upon the light intensity, the pH of the solution, the type and concentration of catalyst used for the water reduction step and the concentrations of chromophore, EDTA and methyl viologen. These factors were optimised for H2 production and alternative types of viologen were tried but none was superior to methyl viologen. The significance of these findings towards the cyclic cleavage of water into H2 and O2 is described briefly.
