Project Title

Modified Mesoporous Silica Membranes for Separation Applications

Project Description

This project represents an effort to synthesize membranes of mesoporous silica materials, to functionalize these membranes with functional groups, and to study and optimize their performance in separation applications. The fabrication of mesoporous silicate films has long been of interest for a variety of applications. Through these pore sizes preclude direct application in molecular separation, it has been recently shown by Dr. Jones that mesoporous silica powder materials can be amine-functionalized to yield a high concentration of amine groups inside the pores. This in turns leads to an unusually high CO2 sorption capacity. Similar results may be expected for H2S sorption. While the current results hold high promise, it is a significant challenge to develop novel membrane technologies based on the above concept.
