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.

Key words: Periodic mesoporous organosilica, Nanomaterials, Integrated experiment
