Abstract: A novel class of nano-carbon materials called as luminescent carbon quantum dots (CQDs) has received a most of attention lately, specially in the fields of chemical sensors, bio-imaging, nano-medicine, solar cells, lightemitting diode (LED), and electro catalysis. Many methods, including the arc-discharge method, microwave pyrolysis, hydro-thermal process, and electro-chemical synthesis, can be used to make CQDs quickly and affordably. CQDs have outstanding chemical and physical characteristics, including high crystallisation, good dispersibility, and photoluminescence. Particularly, the CQDs-based composite has high electric conductivity and catalytic activity due to the small size, superconductivity, and quick electron transfer of CQDs. Additionally, CQDs have a lot of surface functional groups, which could make it easier to make multi-component electrical active catalysts. As a result of interactions within these multicomponent catalysts, charge transfer, a crucial electrochemical process, may be promoted, which could further improve the catalytic performance. Recent studies on CQDs have concentrated on their photocatalytic and fluorescence features. This review summarize the different approaches for the synthesis of C-QDs and the properties in the different field of science.
