Teaching through Research: A Comprehensive Experiment on Carbon Quantum Dots from Microplastic Waste

School of Chemistry and Life Resources, Renmin University of China, Beijing 100872, China

Received Date: 2 December 2024
Revised Date: 14 February 2025

Microplastic pollution has become a global environmental issue, and transforming it into carbon quantum dots (CQDs) offers an innovative approach to pollution control. In this experiment, CQDs were synthesized using hydrothermal and calcination methods, and their optical properties were systematically analyzed. Additionally, the effect of Fe³⁺ on the fluorescence properties of the CQDs was investigated. The experiment covers the preparation, performance analysis, and Fe³⁺ detection, with a simple and practical procedure. It integrates organic chemistry and environmental chemistry, enhancing the experiment’s engagement and educational value, helping students better understand and apply theoretical knowledge while fostering innovation and practical skills.
