Abstract

This chapter reviews computational studies on the water oxidation mechanisms of mononuclear and dinuclear ruthenium catalysts, the cobalt hangman corrole catalyst, and the iron-TAML catalysts. Diagonal steps are protoncoupled electron transfers (PCET) reactions. The relevance of a first solvation-shell water molecule was considered through extensive conformational searches as a hydrogen-bonding network could stabilize the conjugate base and acid forms of the-CO2H moiety. The chapter reports only the free energy of the most stable conformer in each case. It presents the results of a density functional theory (DFT) study together with multireference second-order perturbation theory to elucidate the mechanism of water oxidation in the iron(III)-centered tetraamido macrocyclic ligand (FeIII-TAML) catalyst.
