Synthesis of Novel Microporous Solids Containing Vanadium

本研究的目的是合成具有特定有机分子吸附中心的新型有机-无机层状结构，并研究基于四面体含氧阴离子的VO5四方金字塔连接骨架的新型扩展晶格的合成。随后从固体中去除客体物种导致化合物在随后的反应中表现出高度选择性的分子吸附和离子络合。用粉末和单晶衍射法、磁化率测量、吸附等温线和动力学测定对新相进行了表征。这些研究在涉及燃料和化学品生产的过程的催化方面具有特殊的价值。

The objectives of this research are to synthesize new organic- inorganic layered structured with adsorption sites for specific organic molecules and to investigate the synthesis of new extended lattices based on connected frameworks of VO5 square pyramids with tetrahedral oxyanions. Subsequent removal of the guest species from the solid leads to compounds which can show highly selective molecular sorption and ion complexation in subsequent reactions. The new phases will be characterized by powder and single crystal diffraction methods, magnetic susceptibility measurements and the determination of sorption isotherms and kinetics. These studies are of special value in catalysis for processes involving the production of fuels and chemicals.
