Synthesis of Metal Oxides with Open Framework Structures

该项目旨在利用水热合成技术扩展金属氧化物的无机材料化学，特别是发现新的开放骨架结构，具有用作吸附剂或多相催化剂的潜力。一个重要的方向是强调具有稳定性和晶内反应性的微孔固体。两类主要的无机材料已经成为目标，VB族过渡金属磷酸盐和VB族过渡金属硅酸盐和锗酸盐。初步研究表明，可以构建许多新的微孔骨架硅酸盐，这是该研究的一个主要焦点。将开发的新合成技术包括修改标准水热反应条件和在必要时使用更高的压力。注重本科生和研究生的培养。特别是，将强调妇女和其他任职人数不足的群体参与研究。性能得到改善的新型纳米多孔无机固体将在分子分离和化学反应中用作催化剂，对于石油化工行业在炼油和化学品生产等领域的需求至关重要。化学加工的改进对于更有效地利用美国的碳氢资源和提高能源效率非常重要。

This project aims to use hydrothermal synthesis techniques to expand the inorganic materials chemistry of metal oxides and specifically to discover new open framework structures with potential for use as sorbents or heterogeneous catalysts. An important direction is an emphasis on microporous solids with stability and intracrystalline reactivity. Two major classes of inorganic materials have been targeted, the group VB transition metal phosphates, and the group VB transition metal silicates and germanates. Initial studies indicate that many new microporous framework silicates can be constructed and this a major focus of the research. New synthesis techniques that will be developed include the modification of standard hydrothermal reaction conditions and the use of higher pressures where necessary. Training of both undergraduate and graduate students will be emphasized. In particular the participation of women and other underrepresented groups in the research will be emphasized. New nanoporous inorganic solids with improved properties that will have applications in molecule separations and as catalysts in chemical reactions are vital to the needs of the petrochemical industry in areas that include oil refining and chemicals production. Improvements in chemical processing are important for more effective use of U.S. hydrocarbon resources and to increase energy efficiency.
