RT Journal Article T1 Oxygen reduction using a metal-free naphthalene diimide-based covalent organic framework electrocatalyst A1 Royuela, Segio A1 Martínez-Periñán, Emiliano A1 Arrieta, Marina P. A1 Martínez, José I. A1 Ramos, Mar M. A1 Zamora, Félix A1 Lorenzo, Encarnación A1 Segura Castedo, José Luis AB A novel naphthalene diimide-based covalent organic framework (NDI-COF) has been synthesized and successfully exfoliated into COF nanosheets (CONs). Electrochemical measurements reveal that the naphthalene diimide units incorporated into NDI-CONs act as efficient electrocatalyst for oxygen reduction in alkaline media, showing its potential for the development of metal-free fuel cells.
