Bifunctional Catalysts for CO2 Reduction
Abstract
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 salen/salan 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.
