模拟太阳光下驱动H2O2生成及含量测定的综合实验.

With the backdrop of "Carbon peaking and carbon neutrality goals", the development of renewable energy and solar energy storage has gained countless attention recently. However, the lack of experiments involving energy conversion in undergraduate curricula has limited students' understanding of low-carbon and green chemistry to remain largely theoretical. This experimental protocol aims to synthesize hydrogen peroxide (H2O2), utilizing the solarto-chemical conversion, all while aligning with cutting-edge scientific advancements. The entire experimental process refrains from the use of any toxic or hazardous reagents, truly embodying the principles of green and low-carbon chemistry. Illustrating with the synthesis of graphitic carbon nitride (g-C3N4) nanosheets via dicyandiamide, this experiment delves into the mechanism of polymerization reaction. This approach integrates fundamental operations from inorganic, physical, and analytical chemistry, coupled with modern analytical methods, to conduct open-ended comprehensive experiments on the g-C3N4 catalyzed generation of H2O2 and quantification. By combining the polymerization reaction of inorganic and organic materials within an aerobic experimental environment and employing UV spectrophotometry for yield measurement, this experiment effectively enhances students' comprehensive qualities and innovative abilities, achieving the goal of "integrating current affairs into teaching and cultivating well-rounded students".
