Different Methods for Removal of Mesoporous Silica Organic Template Agent
摘要
Abstract
Development of mesoporous materials, removing problem of template agent has not been solved.In order to better solve the problem of removing organ-template agent of mesoporous silica,it was proposed the method of calcination, extracting and combining calcination with extracting to remove organic template agent of mesoporous silica.The structural properties of the materials were analyzed by Transmission Electron Microscopy(TEM),Nitrogen adsorption/desorption the Fourier infrared and Thermogravimetry Analysis(TGA)characterization methods,etc.The results indicate that MSN-A(450℃calcination)of pore diameter(4.8 nm), pore volume(0.558 cm3· g-1)and the specific surface area(604.64 m2· g-1)is the biggest.The article processed systemic research for the several methods, getting result.The conclusions about how to quickly choose the method of removing template agent possess guiding significance.关键词
