The Preparation and Application of Modified Graphene Carbon Quantum Dots

Currently, there are few integrative experimental designs about the synthesis of nanomolecular polymer in the teaching of basic chemistry experiments in our country, and there is a lack of relevant experimental teaching close to the direction of scientific research. Graphene Carbon Quantum Dots (GCQDs) are new carbon nanomaterials based on graphene materials, and the modified GCQDs will have excellent performances. Herein, we define AGQDs as graphene carbon quantum dots functionalized with l-aspartic acid, synthesized via a one-pot hydrothermal method. Based on the basic chemical and microbial experiments, the experiment includes the selection and synthesis of raw materials and the preparation and characterization of AGQDs, and the multiphase teaching module of its application is studied from different angles. In this experiment, students, as the main body, are guided to think independently, which is helpful to enhance students’ cognition of nanomaterials, improve students’ ability of scientific innovation, and stimulate students’ interest in scientific research.
