The widespread utilization of renewable energy will require energy dense and cost-effective methods for storage. This challenge could be met by coupling renewable electricity to the reduction of carbon dioxide or protons and the oxidation of water to O2, providing, in net, a viable scheme for artificial photosynthesis. Realizing this goal requires the development of new electrocatalysts with enhanced selectivity, efficiency, and durability.
We are developing strategies for promoting inner-sphere fuel formation electrocatalysis at extended solid surfaces by grafting rigid polyfunctional ligands that are able to interact synergistically with proximate active sites. Although numerous methods exist for the chemical modification of thin film and nanostructured electrodes, surface functionalization typically serves to completely passivate active sites, inhibiting their participation in substrate activation or bond-formation, rending the electrode catalytically inert. We have recently developed synthetic strategies for overcoming this obstacle allowing for the catalytic promotion of fuel formation via chemical modification. Our current strategies and recent results will be highlighted.
