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.

该项目旨在使用水热合成技术来扩展金属氧化物的无机材料化学性质，特别是发现新的开放式框架结构，并有可能用作吸附剂或异质催化剂。一个重要的方向是强调具有稳定性和晶体内反应性的微孔固体。已经针对了两种主要的无机材料，即VB组过渡金属磷酸盐，以及Vb组过渡金属硅酸盐和德国盐。初步研究表明，可以构建许多新的微孔框架硅酸盐，这是研究的主要重点。将开发的新合成技术包括对标准水热反应条件的修改以及必要时使用更高的压力。将强调对本科和研究生的培训。特别是将强调妇女和其他代表性不足的群体的参与。具有改进特性的新型纳米多孔无机固体将在分子分离中应用，并且作为化学反应中的催化剂在包括炼油和化学物质生产在内的区域中对石化工业的需求至关重要。化学处理的改进对于更有效地利用美国烃资源并提高能源效率很重要。
