Abstract

Novel material innovation is a driving force for advancing high-performance electrochemical energy storage technologies. Quantum dots (QDs), over the last decade, have exhibited immense potential in applications related to bioimaging, optoelectronics, catalysis, and energy storage, together with a remarkable rise in greener synthesis methods. Carbon nanomaterials, particularly carbon quantum dots (CQDs) and graphene quantum dots (GQDs), have garnered significant interest due to their exceptional characteristics, including high electrical conductivity, thermal stability, mechanical robustness, chemical durability, photoluminescence, affordability, and ease of surface modification. CQDs show promise for supercapacitors due to their unique properties but face challenges like limited surface area. Improving CQD synthesis and purification is crucial for enhancing supercapacitor performance. GQDs are praised for their conductive networks and surface properties, but more research is needed on industrial-scale synthesis. This review reported the recent advances in the electrochemical characteristics and synthesis of various QDs in supercapacitor electrodes.

期刊介绍： Electrochemistry Communications is an open access journal providing fast dissemination of short communications, full communications and mini reviews covering the whole field of electrochemistry which merit urgent publication. Short communications are limited to a maximum of 20,000 characters (including spaces) while full communications and mini reviews are limited to 25,000 characters (including spaces). Supplementary information is permitted for full communications and mini reviews but not for short communications. We aim to be the fastest journal in electrochemistry for these types of papers.
