RT Journal Article T1 Synthesis of modified fullerenes for oxygen reduction reactions A1 Girón, Rosa María A1 Martínez, Juan Marco A1 Bellani, Sabastiano A1 Insuasty, Alberto A1 Comas Rojas, Hansel A1 Antognazza, María Rosa A1 Filippone, Salvatore A1 Martín, Nazario AB In the search for carbon based catalysts for Oxygen Reduction Reactions (ORR), two different classes of fullerene hybrids and metal free fullerene derivatives have been prepared by highly selective metal- and organo-catalyzed synthetic methods. They were included as both electron acceptors and catalysts in polymer-based photo-electrochemical cell,fully demonstrating electrocatalytic activity. Remarkably, the activity of the metal free fullerenes proved to be as high as that observed for metallofullerenes based on noble metals, and up to ten-fold higher than by using PCBM.
