研究目的
Investigating the synthesis of graphene quantum dots stabilized copper nanoparticles and their applications in the CuAAC reaction and 4-nitrophenol reduction.
研究成果
A green and facile method of synthesis of graphene quantum dots stabilized CuNPs has been developed. CuNP-3 exhibits excellent catalytic performance in the CuAAC reaction and has also been successfully applied in the reduction of 4-nitrophenol with excellent catalytic activity. The graphene quantum dots stabilized CuNPs show wide potential applications in cell image, sensor, and catalysis fields.

The technical and application constraints of the experiments, as well as potential areas for optimization, are not explicitly mentioned in the abstract.
1：Experimental Design and Method Selection:
The synthesis of GQDs-stabilized CuNPs was conducted by using GQDs A and sodium borohydride dissolved in water, followed by the addition of different amounts of CuSO4·5H2O at 0 ℃, respectively.
2：Sample Selection and Data Sources:
GQDs A with the size from
3：25 to 50 nm has been synthesized from only commercial starch and water. List of Experimental Equipment and Materials:
GQDs, NaBH4, CuSO4·5H2O, deionized water.
4：Experimental Procedures and Operational Workflow:
The solution is stirred for 30 mins after adding NaBH4, then CuSO4 is added dropwise, provoking the formation of yellow color, corresponding to the reduction of the cation to the zero-valent metal and CuNP-3 formation.
5：Data Analysis Methods:
The CuNP-3 has been characterized by UV-vis spectroscopy, TEM, XRD and XPS.
