摘要: 近年来，新能源研发和太阳能储能在“双碳”背景下受到广大学生的关注。然而，在本科生教学实验中，缺乏涉及能源转换的实验，导致学生对低碳和绿色化学的理解停留在理论层面。本实验方案深入结合科学前沿的热门领域，利用模拟太阳光制备过氧化氢（H₂O₂），实现太阳能到化学能的转换和储存。整个实验过程不使用任何有毒有害试剂，充分体现绿色低碳的化学宗旨。本实验以双氰胺合成石墨相氮化碳（g-C₃N₄）纳米片为例，分析聚合反应机制，充分融合了无机、物化和分析的基本操作，同时结合一些现代分析手段，进行g-C₃N₄催化H₂O₂生成和含量测定的开放性综合实验。实验中结合无机到有机材料的聚合反应，基于有氧实验环境的处理，利用紫外分光光度计测定产率，可有效提升学生的综合素质和创新能力，实现了“融时政于教学，培育全面发展的学生”的目标。

Abstract: 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 solar-to-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".
