Presentation Transcript

    1. Uranyl Mesoporous Materials Alex Burum Dr. Peter Burns Ginger Sigmon University of Notre Dame-Summer 2006 REU

    2. Overview Background Synthesis Results

    3. Why mesoporous materials? Mesoporous materials have pore sizes 20-500Ĺ Zeolites are limited to ~15Ĺ pore sizes Applications Catalysts Molecular Sieves

    4. Why uranyl mesoporous materials? Use of depleted uranium Materials New catalyst for environmental breakdown Nuclear waste form

    6. Synthesis Anions + uranyl nitrate + surfactant + urea + water = U mesoporous material (1-x) : (x) : 2 : 30 : 60 (NH2)2CO + 3H2O = 2NH4+ + 2OH- + CO2

    7. Synthesis Anions + uranyl nitrate + surfactant + urea + water = U mesoporous material (1-x) : (x) : 2 : 30 : 60

    8. Synthesis Anions + uranyl nitrate + surfactant + urea + water = U mesoporous material (1-x) : (x) : 2 : 30 : 60
