Electrocatalytic Water Oxidation to Dioxygen in Molecular PdII/IV Coordination Environment


Dmitry Yandulov, Department of Chemistry, Stanford University


The goal of this exploratory project is to find electrocatalysts for the oxidation of water to oxygen at close to the thermodynamic potential. A new mechanistic approach will be explored using well-defined coordination complexes of PdII-IV. The proposed studies will test the feasibility of the key elementary steps of the proposed reaction mechanism and provide the foundation necessary for systematic improvement of water oxidation catalysis efficiency by design. The studies will begin with ligand and PdII complex synthesis, evaluation of aqueous pH stability limits of representative PdII(N-heterocyclic carbene) complexes, and screening of catalytic activity in water oxidation with Ce4+.
