双碳背景下光催化水分解制绿氢实验教学实践研究

Experimental Teaching Practice on Photocatalytic Water Splitting to Produce Green Hydrogen under Double-carbon Background

太阳能的开发和利用是缓解全球能源危机和环境问题的有效途径之一。光催化技术是一种高效利用太阳能的能源生产和减少环境污染的技术。为了让学生对光催化材料的制备、表征、分析有更深入的了解,本实验结合教师的研究方向选取石墨相C_(3)N_(4)作为研究对象,利用UV-Vis紫外可见分光光度计、XRD、TEM、气相色谱等设备对光催化材料的结构与相关性能进行研究。该实验涵盖了材料制备、材料表征、光催化产氢等实验环节,结合了绿色化学的理念,促进学生对理论知识和实践相结合,培养提高本科生的科学素质。

The exploration and use of solar energy is one of the effective ways to alleviate the global energy crisis and environmental problems.Photocatalytic technology is a high-efficient technique to utilize solar energy for energy production and reducing environmental pollution.To let students have a deeper understanding of the preparation,the characterizations and analysis of photocatalytic materials,these experiments combined teachers'research direction to select graphite phase C_(3)N_(4) as the research object,and UV-Vis spectrophotometer,XRD,TEM,GC and other equipments were used to study the structures and the related properties of photocatalytic materials.The experiment covered the experimental aspects of material preparation,material characterization,and photocatalytic hydrogen production,which combined the concept of green chemistry,promoted the combination of students'theoretical knowledge and practice,developed and improved undergraduates'scientific quality.
