A Model for Water Oxidation Complex in Photosystem II

M. Mahdi Najafpour
Ruthenium complexes containing ring-substituted bipryidine ligands and related structures have longbeen known to efficiently catalyze water oxidation by strong chemical oxidants and at electrode surfaces. However, despite considerable effort, the goal of identifying the underlying molecular mechanisms has not yet been realized. In this paper, ZINDO/1 theory has been used to study a Ru complex found to react with water and Ce(NH 4)2(NO3)6 to liberate molecular oxygen (O2). The complex indicates a robust catalyst as compared to other earlier reported systems also a proposal mechanism for water oxidation is reported.
