Redox catalysis for solar fuel generation

Research output: Contribution to journalConference articlepeer-review


We are carrying out coordinated experimental and theoretical studies of redox catalysts for solar fuel generation by water splitting and CO2 reduction. Our focuses are: optimization of the light-harvesting and charge-separation abilities of stable oxide or oxide-derived semiconductors for solar-driven fuel generation; mechanistic investigation of water oxidation by dinuclear and mononuclear metal complexes having non-innocent quinonoid ligands or pendent bases as proton relays in order to develop a better understanding of the critical water oxidation chemistry, and rationally search for improved catalysts; photoinduced catalytic reduction of CO2 to CO and/or formate, and ultimately to methanol following the concept of coupled proton and hydride-ion transfer reactions; fundamental studies of the thermodynamic, kinetic, and photophysical and photochemical properties of M-H, M-C1, and metal complexes with an NADH-model ligand, and proton-coupled electron-transfer reactions for H2 production from water using earth-abundant transition-metal complexes with pendent bases as proton relays. Their redox, spectroscopic, and catalytic properties will be discussed.
