Tethering molecular catalysts to semiconductors is an attractive strategy for the conversion of CO2 to fuels and commodity chemicals using renewable energy sources. This presentation will first describe tethering strategies for the attachment of the well-known molecular CO2 reduction catalyst, Re(bpy)(CO)3Cl, to doped Si surfaces. Preliminary results show that the Re complex can be attached to oxide-coated surfaces using a silatrane-functionalized bpy ligand. To address issues of stability on the surface, different linkers and attachment strategies are also being explored, as well as other catalyst systems. Electrochemical and photoelectrochemical behavior of the hybrid (photo)electrodes under CO2 reduction conditions will be described.
