Popis: Micrometer long multilayer carbon nanoribbons with high oxygen content and nitrogen doping were obtained from the nitric acid treatment of Black Pearls 2000. The nanoribbons (NRs) exhibited yellow light emission under UV excitation. The oxidation of other grades of carbon black yielded irregular and small graphene oxide fragments or carbon quantum dots instead. Remarkably, the familiar and straightforward treatment of carbon materials with nitric acid reemerges as a powerful tool for the synthesis of technology-relevant carbon nanoribbons, and unlocking the potential of such straighforward oxidation chemistry applied to inexpensive and commercially available carbon black.
