- Abstract
- Since their discovery in 2004, carbon dots (CDs), a key component in the field of carbon nanomaterials, have attracted considerable interest. CDs are a new variety of carbon allotropes, alongside graphite, carbon nanotubes and activated carbon. They have attracted widespread attention because of their excellent applications in a variety of fields, thanks to their remarkable properties. CDs have shown particular promise because of their excellent properties, including small size, remarkable biocompatibility, optical brightness, catalytic efficiency, environmental friendliness and low toxicity. They are increasingly used in a variety of fields, including Li-O2 batteries, where they have achieved a high specific capacity of 7500 mAh g−1 over 100 cycles, and in fluorescent detection. In the latter application, CDs have been used for the selective and sensitive detection of Fe3+ ions by exploiting the fluorescence quenching of CDs, with a remarkable detection limit of 0.66 µM in the concentration range from 5 to 25 µM. CDs are also widely used in catalysis, optoelectronic devices, biomedicine, lubrication and other industries, demonstrating their versatility and potential in many fields. © 2023 Elsevier B.V.
