Synthesis of Graphene Quantum Dots Stabilized CuNPs and Their Applications in CuAAC Reaction and 4-Nitrophenol Reduction

Publication date: Available online 21 October 2019Source: Inorganic Chemistry CommunicationsAuthor(s): Yu Huang, Weifeng Chen, Jialu Shen, Yanlan Wang, Xiang LiuAbstractHere we report the synthesis of graphene quantum dots (GQDs) stabilized copper nanoparticles in neat water. Construction of six CuNPs 1-6 nanocomposites are accomplished by mixing GQDs and NaBH4, and followed by the addition of different amounts of copper sulfate at 0 ℃ in water, respectively. Among them, CuNP-3, with the size of 2.6 nm, exhibits excellent catalytic performance in the CuAAC reaction over than other CuNPs. Moreover, the CuNP-3 has also been successfully applied for the reduction of 4-nitrophenol with excellent catalytic activity.Graphical abstractHere we report the synthesis of graphene quantum dots (GQDs) stabilized copper nanoparticles in water. The as-synthesized nanoparticles show high catalytic activity in the “click” reaction and reduction of 4-nitrophenol
