Abstract: This innovative comprehensive experiment aims to develop a teaching concept based on “green chemistry” by integrating theoretical knowledge of literature retrieval, inorganic synthesis, instrumental analytical chemistry and electrochemistry. Emphasizing chemical recycling, reuse and repurposing of waste, the experiment deepens students’ understanding of basic chemistry principles, promotes innovative thinking, and enhances their innovation consciousness. Taking carbon quantum dots and energy storage as the entry point, the research focuses on carbon quantum dots obtained from the hydrothermal reaction of rice husk, aiming to explore the relationship between their structure and properties. Through experimental design, result analysis and collaborative discussion, students can gain insights into the interdisciplinary potential of “agriculture and science” integration and the fusion of science and education. This approach effectively improves students’ practical and innovation abilities, and enhances their academic confidence.

Key words: Rice husk, Electrochemistry, Carbon dot, Energy storage
