Eric Hampsey Xuepeng Qiu Lianxun Gao Jibao He Yunfeng Lu 10.1021/cm052764p.s001 https://acs.figshare.com/articles/journal_contribution/Synthesis_and_Characterization_of_Functionalized_Mesoporous_Silica_by_Aerosol_Assisted_Self_Assembly/3224626 An efficient, productive, and low-cost aerosol-assisted self-assembly process has been developed to produce organically modified mesoporous silica particles via a direct co-condensation of silicate species and organosilicates that contain nonhydrolyzable functional groups in the presence of templating surfactant molecules. Different surfactants including cetyltrimethylammonium bromide, nonionic surfactant Brij-56, and triblock copolymer P123 have been used as the structure-directing agents. The organosilanes used in this study include tridecafluoro-1,1,2,2-tetrahydrooctyltriethoxysilane, methytriethoxysilane, vinyltrimethoxysilane, and 3-(trimethoxysilyl)propyl methacrylate. X-ray diffraction and transmission electron microscopy studies indicate the formation of particles with various mesostructures. Fourier transform infrared and solid-state nuclear magnetic resonance spectra confirm the organic ligands are covalently bound to the surface of the silica framework. The porosity, pore size, and surface area of the particles were characterized using nitrogen adsorption and desorption measurements. This method provides a direct synthesis route to efficiently synthesize a large variety of organic functionalized mesoporous silica particles with controlled pore sizes, pore surface chemistry, and pore structures for catalyst, filler, and other applications. 2006-05-02 00:00:00 surface area templating surfactant molecules synthesis route resonance spectra transmission electron microscopy studies pore surface chemistry functionalized mesoporous silica particles silicate species triblock copolymer P 123 pore size Functionalized Mesoporous Silica Different surfactants desorption measurements mesoporous silica particles pore structures pore sizes cetyltrimethylammonium bromide nitrogen adsorption silica framework
