Preparation of Cage Nanoporous Silica and Its Application in Chromatographic Fillers

Journal Title: Nanoscience and Nanotechnology - Year 2017, Vol 1, Issue 1

Abstract

In this paper, the cage nanoporous silica is composed of ethyl orthosilicate as silicon source, triblock copolymer poly (ethylene oxide) -poly (propylene oxide) -polyethylene oxide (F127) as structure guide agent and additive, while the Fm3m cubic structure of cage type nanoporous silica was prepared by hydrothermal synthesis method. It is easy to control the self-assembly of the silica triblock copolymer intermediates thermally. In addition, the change in sample pore size and pore volume can be achieved by a hydrothermal reaction at a temperature of 100 ° C to 150 °C. Small angle X-ray diff raction shows that these samples have ordered pores, while adsorption studies show that they have high porosity, uniform distribution of bimodal pores and large pore volume. Use separation of p-methylbenzene borate, iodobenzene and biphenyl by using three kinds of cage-type nanoporous silica materials as chromatographic fillers. The results showed that the material prepared at 130 ℃ under hydrothermal condition had the best effect on the separation of three organic compounds.
