Integrating Frontier Scientific Research Results into Inorganic Chemistry Experiment Teaching:Synthesis of Magnetic Crystalline Composite Materials Fe3O4@COF-AuNPs
An undergraduate experiment was designed to prepare Fe3O4 by oxid-reduction method and further synthesize magnetic crystalline nanomaterials Fe3O4@COF-AuNPs.Firstly,ferric oxide was prepared by reduction-oxidation(REDOX)method,followed by further adsorption of covalent organic framework(COF)crystalline material.Finally,the Au nanoparticles(AuNPs)were embedded in Fe3O4@COF NPs to form Fe3O4@COF-AuNPs.This experiment can train students'ability to prepare iron oxide.By combining COFs with other substances,students can understand the properties of COFs crystal materials and master the use of instruments and equipment.By analyzing the microscopic properties of crystals through images and data,students can further understand the forefront of science and thus improve their scientific literacy.
