摘要: 碳捕集技术是实现“双碳”目标的重要途径。高温工业源CO₂的捕集更宜使用钙基吸收剂。本文立足“双碳”背景，将碳捕集前沿技术融入仪器分析实验课程，开发了蛋壳源CaO的制备、表征及其碳捕集性能的设计性综合实验。选择高钙废弃物鸡蛋壳为原料，采用醋酸处理得到醋酸钙，再经高温煅烧制备了具有较好碳捕集性能的CaO;利用EDTA配位滴定、扫描电子显微镜、X射线衍射、红外光谱、拉曼光谱和热重分析等多种分析手段，测试了CaO的纯度、形貌、结构及其对CO₂的捕集性能。本实验采用项目式教学方式，引导学生自行设计实验方案并进行实践和总结，不仅锻炼了学生综合运用专业知识解决实际问题的能力，而且培养了学生的科研素养和团队合作精神。

Abstract: The carbon capture technology is an important way for achieving the “Double Carbon” goal. Calcium-based absorbents are more suitable for the capture of CO₂ from high-temperature industrial sources. Based on the context of the “Double Carbon”, this work integrated cutting-edge carbon capture technology into instrumental analysis experimental course, and developed a designing and comprehensive experiment about “preparation, characterization and carbon-capture ability of eggshell-derived CaO”. Waste eggshells was selected as the calcium source, then pre-treatment with acetic acid yielded calcium acetate, which was calcined at high temperatures to produce CaO with good carbon capture ability. The purity, morphology, structure, and CO₂capture ability of as-prepared CaO were tested using various analysis methods such as EDTA compleximetry titration, scanning electron microscopy, X-ray diffraction, infrared spectroscopy, Raman spectroscopy, and thermogravimetric analysis. This experiment adopts a project-based teaching approach, which guides students to independently design experimental plans, conduct practical work, and summarize their findings. It not only enhances students’ ability to comprehensively apply professional knowledge to solve practical problems, but also cultivates their scientific research literacy and teamwork spirit.
