Title: Graphene as Redox Non-Innocent Ligands for Electrocatalytic Multielectron Reduction
Graphitic carbon such as charcoal and activated carbon have been widely used in catalysis, either as catalysts themselves or as supports for other catalysts. However, a molecular-level understanding of their roles in these processes has been lacking. To address this challenge, we have developed well-defined colloidal graphene quantum dots (GQDs) to understand and control fundamental processes in carbon catalysis. In my talk I will present our work on N-doped GQDs as agents for multielectron reduction reactions. The N-doped GQDs can catalyze the oxygen reduction reaction (ORR). They can also be used as a new type of redox non-innocent ligands for metal ions to electro- and photochemically catalyze CO2 reduction.
