Studies of Transition Metal Ions on Oxide Surfaces by Electron Magnetic Resonance

分析和表面化学项目的目标是探索微孔分子筛氧化物中吸附的过渡金属离子的结构。凯文教授和他的团队将发展电子磁共振方法并将其应用于这些体系，并将获得有关吸附的过渡金属离子与氧化物载体骨架核之间相互作用的详细信息。还将对表征材料的催化活性进行比较。开发先进的电子磁共振波谱方法是这项工作的另一个重要目标。这项工作将对氧化物负载的过渡金属离子作为催化体系的结构进行表征。这一表征对于进一步设计和理解用于石油精炼和化工过程工业的具有重要技术意义的氧化物载体催化剂至关重要。

The goal of this project in the Analytical and Surface Chemistry program is to probe the structure of transition metal ions adsorbed in microporous molecular sieve oxides. Electron magnetic resonance methods will be developed and applied to these systems by Professor Kevan and his group, and detailed information about the interaction between the adsorbed transition metal ion and the framework nuclei of the oxide support will be obtained. Comparisons will also be made to catalytic activity of the characterized materials. Development of advanced electron magnetic resonance spectroscopic methods is an additional important goal of this work. %%% Structural characterization of oxide supported transition metal ions which are useful as catalytic systems will result from this work. This characterization will be crucial to the further design and understanding of technologically important oxide supported catalysts used in petroleum refining and chemical process industries.
