The recent discovery of regular hexagonal mesoporous silicas (HMS) by the Mobil group in 1992 has spawned a large research activity into the possible catalytic and adsorptive properties of these materials.  In unmodified form, HMS materials are poor adsorbents with little adsorptive capacity and selectivity.  However, by suitable chemical modification and tethering, it is possible to greatly enhance the adsorptive properties of these materials.  In this research project (in collaboration with Dr. Alan Chaffee in the Department of Chemistry), we are exploring chemical modification of MCM-41 to produce CO2 adsorbents and O2 adsorbents which are tolerant to moisture and have comparable capacity to zeolitic materials.
