摘　　要：设计了一种氧化还原方法制备四氧化三铁,并进一步合成Fe_(3)O_(4)@COF-AuNPs磁性晶态纳米材料的本科生化学实验。首先通过氧化还原方法制备四氧化三铁,再进一步吸附共价有机框架COF晶态材料,在Fe_(3)O_(4)@COFNPs中嵌入金纳米粒子,最终形成Fe_(3)O_(4)@COF-AuNPs。本实验可以锻炼学生制备四氧化三铁的能力,利用COFs与其他物质的结合,使学生熟悉COFs晶态材料的性质,掌握仪器设备的使用。通过图片以及数据,分析其微观性质,使学生进一步了解科学前沿,提升科学素养。An undergraduate experiment was designed to prepare Fe_(3)O_(4) by oxid-reduction method and further synthesize magnetic crystalline nanomaterials Fe_(3)O_(4)@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 Fe_(3)O_(4)@COF NPs to form Fe_(3)O_(4)@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.
