Multinuclear Solid-State NMR Investigation of Cocation Effects in Group VIII Metal-Exchange Zeolites

该项目属于分析化学和表面化学的一般领域，以及固态核磁共振波谱学和多相催化的子领域。本研究项目将通过固态核磁共振波谱研究酸性共阳离子对沸石上负载的第八族金属的电子和几何结构以及化学吸附性能的影响。本研究的目的是了解酸性共阳离子如何在选择性和稳定性方面提高沉积在沸石上的VIII族金属的催化性能。从这项研究中获得的见解可能会导致制备用于从天然气合成液体燃料的改进费托沸石催化剂。

This project is in the general area of analytical and surface chemistry and in the subfields of solid-state nuclear magnetic resonance spectroscopy and heterogeneous catalysis. This research program will investigate by means of solid-state nuclear magnetic resonance spectroscopy the effects of acidic co-cations on electronic and geometrical structures and chemisorption properties of the Group VIII metals supported on zeolites. The aim of this research is to understand how acidic co-cations can improve the catalytic performance of the Group VIII metals deposited on zeolites in terms of selectivity and stability. Insight gained from this research may lead to the preparation of improved Fischer-Tropsch zeolite catalysts used for synthesis of liquid fuels from natural gases.
