水的减少已经通过原位形成的基于非贵金属的均相催化剂系统实现。优化的配体量增加催化剂周转数相比，预制的配合物。机理研究证实了杂配铜配合物作为活性光敏剂（PS）和原位形成的Fe-磷二聚体配合物作为水还原催化剂。原位方法已被用于筛选活性PS的一系列配体，这导致了对寿命和性能重要的许多结构特征的鉴定。
The reduction of water has been achieved through a non-noble-metal-based homogeneous catalyst system that is formed in situ. Optimisation of the ligand quantities increased catalyst turnover numbers compared to preformed complexes. Mechanistic studies confirm a heteroleptic Cu complex as the active photosensitiser (PS) and an in situ formed Fe-phosphido dimer complex as the water reduction catalyst. The in situ method has been used to screen a range of ligands for the active PS, which has led to the identification a number of structural features important to longevity and performance.
