In concert with experiments, these tools can be used for improving catalytic processes for sustainable fuel synthesis. First, I will describe how we are employing density functional theory (DFT) to understand the (photo-)electrocatalytic activity of materials to reduce CO2 to hydrocarbons (solar fuels). We have identified the elementary mechanisms that make this transformation possible and have shown that the protonation of adsorbed CO dictates the overall efficiency of the transformation. By using computational screening tools, we are discovering new candidate materials that can reduce the overpotential of this step, which may help to make solar fuels technologically and economically feasible. In the second part of the talk, I will show how creative catalyst design can enable the development of an efficient and adaptable biorefinery that produces the light end (C0-C3) product spectrum of a conventional refinery. The design of catalysts that can perform decarboxylation reactions without being subject to CO fouling will be key in this development, as will the design of catalysts for the selective synthesis of gasoline-range hydrocarbons from light-end feedstocks. These advances can lead to flexible biorefineries that are adaptable to changing market dynamics.
