Abstract [en]

The presence of oxo and carboxylate ligands is crucial to decreasing the redox potentials of the oxygen evolving complex (OEC). It has been proved that negatively charged ligands can stabilize the high oxidation states of various transition metal-based complexes and lower their oxidation potentials. This chapter focuses on complexation of transition metals primarily ruthenium (Ru) with carboxylate-containing ligands, in order to develop artificial water oxidation catalysts (WOCs) with small overpotentials. The authors aim at applying highly active and robust WOCs in artificial photosynthesis devices that convert photo energy to chemical energy. A typical visible light-driven water oxidation system consists of three components: a WOC, a photosensitizer, and a sacrificial electron acceptor. The chapter demonstrates a density functional theory (DFT)-directed development of robust Ru-WOCs, showing one of the advantages of molecular WOCs.
