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。

Abstract:

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 SiO2 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.
