So-Called “Metal-Free” Oxygen Reduction at Graphene Nanoribbons is in fact Metal Driven

The oxygen reduction reaction (ORR) is of key importance in the field of electrochemical energy production. Remarkable catalytic properties of metal-free graphene nanoribbons towards the ORR were suggested in previous reports. Herein, we show that the electrocatalytic properties of an undoped supposedly metal-free graphene nanoribbon towards the ORR is actually caused by metallic impurities within …

Electrochemically reduced graphene nanoribbons: Interference from inherent electrochemistry of the material in DPV studies

Graphene nanoribbons (GNRs) are attracting the interest of scientific community due to the outstanding versatility of their properties and applications. One of the most successful routes for the production of GNRs is the oxidative unzipping of carbon nanotubes followed by electrochemical reduction of oxygen functionalities. Electrochemically reduced graphene nanoribbons may present a reduced anodic potential …
