Synthesis and Characterization of Homogeneous Water Oxidation Catalyst Containing Single Metal Site

Abstract

The aim of this paper has been to design & synthesize Ru complexes for water oxidation catalyst & understood their catalytic mechanism. The main strategy has been to lower the oxidation potential of Ru complex &stabilizes their high valent state by introducing negatively charged ligand. So in this project we are going to synthesize mononuclear Ruthenium water oxidation catalyst for water oxidation, containing one tridentate ligand & one bidentate ligand & one water molecule. We used here Ruthenium based mononuclear complexes because of their favorable properties viz kinetic ligand-exchange, variable oxidation states and coordination numbers under physiological conditions. Since last two decades variety of transition metal complexes have been studied as catalysts for oxidation of water containing Mn, Fe, Co, Ir, Cu and Ru metals. Among the most effective of these catalysts are based on Ru (II).
