摘　　要：设计了g-C3N4基纳米复合物的制备、表征及其光催化性能分析的科学研究型综合实验。通过简单的一步煅烧法合成了α-Fe2O3/g-C3N4纳米复合光催化剂;采用X射线衍射、透射电镜、紫外-可见漫反射光谱等对其结构和性质进行了分析和表征;在模拟可见光照射下,通过测试模型污染物罗丹明B(Rhodamine-B,RhB)的降解程度来考察其光催化性能。实验设计简单易行,涵盖了材料的合成、表征及光催化性能评价等多个知识点,便于学生了解光催化领域的学术前沿,掌握纳米复合材料的制备方法,熟悉大型仪器的使用步骤,同时有助于增强学生的科研创新意识,培养学生的综合实践能力。The comprehensive experiment of the synthesis, characterization and research of photocatalytic activity of g-C3N4 based nano-compounds is designed. In the experiment, the α-Fe2O3/g-C3N4 photocatalysts are prepared via a simple one-step calcination method. The obtained samples are characterized through XRD, TEM, FT-IR and UV-visible diffuse reflection. Irradiated by simulated sunlight, the photocatalytic activity is investigated by the degradation of Rhodamine-B(RhB). The design of experiment is simple and accessible, which covers several knowledges such as preparation of nanomaterials, characteristic techniques and photocatalysis performance, etc. The results show that the comprehensive experiment is helpful to extend students’ understanding of the frontiers of photocatalytic research, grasp the method of preparation of nanomaterials and familiarize the steps of large-scale instruments, which will enhance their comprehensive application consciousness of scientific research and cultivate their practical innovation ability.
