近红外光敏剂制备及光催化性能综合型教学实验的设计与实践

Comprehensive teaching experiment on preparation of near-infrared photosensitizer and its photocatalytic performance

为强化学生的“碳中和”理念和科研创新能力,文章设计了过渡金属硫化物基光敏剂制备及光催化性能综合型教学实验,并通过大学生创新实验形式对该教学内容进行了实践教学。实验教学结果表明:通过对近红外光催化剂制备、结构和光化学性质表征及性能评价等多个环节的设计,使学生切身感受到了光能的魅力;通过探讨光催化过程中选择性氧化的机理,加深了学生对光催化理论知识的理解,激发了他们的科研兴趣,促进了他们创新能力的提升。

To strengthen students’concept of“Carbon neutrality”and the capability of the research and innovation,a comprehensive teaching experiment is designed to prepare transition metal sulfide-based photosensitizers,and the teaching content was carried out in the form of college students’innovative experiments.Through the design of multiple practical links,such as the preparation of near-infrared photosensitizer,characterization of the structure and photochemical properties,and evaluation catalysis performance,students can directly feel the charm of light energy.By exploring the mechanism of selective oxidation in the photocatalytic process,it can improve students’understanding of the theoretical knowledge of photocatalysis,stimulate their interest in scientific research and promote their innovation ability.
