Due to their cheaper cost and intrinsic low toxicity, carbon nanodots (C-dots) have the potential to replace traditional semiconductor quantum dots. To overcome some of the drawbacks with previous methods of fabricating C-dots, Zhenui Kang and his team at Soochow University, China have developed a facile one step electrochemical synthesis. This exciting new method produces c-dots of high purity and uses only pure water as an electrolyte, which is attractive because it is low cost and more environmentally friendly .
The team also synthesized nanohybrid TiO2/C-dots which possess good photocatalytic activity.
To find out more about the photoluminescence and photocatalytic properties of C-dots, read the full Dalton Transactions article…
