摘　　要：本实验围绕中空介孔有机硅纳米材料前沿制备方法,采用逐层包覆与同步生长诱导腐蚀法相结合的方法,设计了一个简单、有效和可控的PMO系列材料制备的综合性教学实验,分别制备了单分散SiO2纳米球和中空介孔有机硅纳米球(Et-HPMO),并通过红外光谱(IR)、扫描电镜(SEM)、透射电镜(TEM)及粉末X射线衍射(PXRD)表征纳米材料的化学组成、微观形貌及介孔结构。使学生学习PMO系列纳米材料的设计、制备及表征方法,提高学生的综合性和系统性实验技能,为学生从事先进材料制备打下基础。This paper introduced an integrated experiment focused on the preparation technology of mesoporous nanomaterials for the undergraduate laboratory.A simple,efficient and highly controllable method was designed for one-step preparation of the hollow-structured PMO materials via growth-induced etching and layer-by-layer coating procedure.We reported the synthesis of monodispersed Si O2 nanpspheres and Hollow Periodic Mesoporous Organosilica(Et-HPMO).The morphology,pore structure and chemical properties of the composite materials are characterized by Infrared spectrum(IR),scanning electron microscopy(SEM),transmission electron microscope(TEM)and X-ray diffraction(XRD).The students can improve the systematic and comprehensive experimental skills by learning the design,preparation and characterization of series of PMO nanomaterials,which aims at enabling students to lay a good foundation in the advanced materials research.
