摘要
将科研成果融入实验教学,结合分形几何、3D打印和等离子体技术,设计了负载型掺杂光催化剂制备与应用综合实验。实验采用原位配位辅助沉积(ISCAP),将硫化镉和锌掺杂的硫化镉化学固定在分形有机载体表面。通过扫描电子显微镜(SEM)、紫外可见漫反射(UV-vis DRS)、X射线光电子谱(XPS)等手段对材料进行了表征。同时,通过对染料罗丹明B(RhB)的降解评估了两种负载型催化剂的光催化活性及稳定性。实验具有综合性、创新性和探究性特点,对学生应用、分析、创造等高阶能力的培养具有促进作用。
Integrating scientific research achievements into experimental teaching,combined with fractal geometry,3D printing and plasma technology,a comprehensive experiment on the preparation and application of supported doped photocatalyst was designed.In-situ complexation-assisted precipitation(ISCAP)method was used to chemically immobilize cadmium sulfide and zinc doped cadmium sulfide on the surface of fractal organic substrate.The materials were characterized by scanning electron microscopy(SEM),UV-Vis diffuse reflectance spectroscopy(DRS)and X-ray photoelectron spectroscopy(XPS).At the same time,the photocatalytic activity and stability of the two supported catalysts were evaluated by the degradation of dye rhodamine B(RHB).The experiment has the characteristics of comprehensiveness,innovation and inquiry,which can promote the cultivation of students’highlevel abilities such as application,analysis and creation.
