摘要: 基于产出导向教育理念，落实以学生为中心的教学策略，以提升人才培养质量为目的，设计并实施了一个科研创新综合训练实验——CdS量子点(CdS QDs)/秩序中孔g-C3N4 (ompg-C3N4)复合光催化剂的制备及其产氢性能研究。实验结果表明：CdS QDs/ompg-C3N4的光催化产氢速率ompg-C3N4的1.8倍，这是因为CdS QDs负载在ompg-C3N4的表面形成了异质结，具有增强的光吸收能力和电荷分离效率。本实验课程的实施，不仅能够训练学生的实验操作技术、数据处理能力，还将学生引入光催化制氢的前沿研究领域，开阔其视野，提升其科研创新的能力，达成课程育人的目标。
Abstract: Based on the concept of output-oriented education, the implementation of student-centered teaching strategy, and the purpose of improving the quality of talent training, a comprehensive training experiment for scientific research and innovation—the preparation of CdS quantum dots (CdS QDs)/ordered mesoporous g-C3N4 (ompg-C3N4) composite photocatalyst and its hydrogen produc-tion performance was designed and implemented. The experimental results show that the photocatalytic hydrogen production rate of CdS QDs/ompg-C3N4 is 1.8 times higher than that of ompg-C3N4, because the CdS QDs loading forms a heterojunction on the surface of ompg-C3N4, it has enhanced light absorption capacity and charge separation efficiency. The implementation of this experimental course can not only train students’ experimental operation technology and data processing ability, but also introduce students to the frontier research field of photocatalytic hydrogen production, broaden their vision, improve their ability of scientific research and innovation, and achieve the goal of educating students.
