Sustainable fuel production requires using renewable energy to power the reductive fixation of carbon dioxide. Although robust technologies are available for converting renewables into electricity, converting electricity to carbon-based fuel is precluded by the lack of effective carbon dioxide electroreduction catalysts. We proposed to prepare bifunctional catalysts that would feature a nucleophilic site to attack the electrophilic carbon of CO2 and an electrophilic site to stabilize the negative charge build-up on oxygen upon CO2 reduction. To achieve this goal, we targeted three families of catalysts 1 modified salensalan dinucleating ligand platforms to form binuclear catalysts 2 dipyrrin-supported complexes that would feature readily tuneable metal-based redox potentials and 3 cluster-based catalysts to reduce CO2 and CO.
