Design of Innovative Experiment for the Continuous Synthesis of Carbon Quantum Dots by Microflow Technique
To explore the innovative teaching mode of interdisciplinary integration at the context of emerging engineering education,and meanwhile,to cultivate chemical engineers with solid theoretical foundation and strong practical ability,a microflow reaction platform was developed and used in the experimental course of chemical engineering for undergraduate.We designed a comprehensive experiment for the synthesis of carbon quantum dots from milk via continuous microflow approach.The composition,structure,and optical properties of carbon quantum dots were characterized by UV-Vis,FT-IR,TEM,XPS,and PL.Through the experiment training,students can get a better understanding of the mechanism and application of microreactor technology,and acquire the relevant operation and characterization skills.Furthermore,the experiment involves the integration of multidisciplinary knowledge including chemistry,chemical engineering,materials,and control,which not only expands students'horizons,but also cultivates their innovation e consciousness,practical skills,and cooperation spirit.
