Presidential Young Investigator Award: Zeolite and MolecularSieve Chemistry

该项目的重点是将金属配合物包封在沸石和分子筛中；将强调三个应用程序。1)新的沸石和分子筛将通过最近开发的方法合成，其中金属配合物在沸石结晶过程中充当模板。2)用氟对稀土沸石进行改性，制备出具有催化裂化应用潜力的新型催化剂。这些催化剂在脱水、脱烷基和歧化反应中更有活性。3)制备并优化沸石基磁共振成像造影剂。达拉斯德克萨斯大学的Kenneth J. Balkus博士是由无机、生物无机和有机金属化学项目支持的总统青年研究员，研究沸石和分子筛的化学。这些材料在工业中大量用作干燥剂和催化剂载体。将合成的新型金属包封材料可作为石油工业的催化剂和磁共振成像造影剂。

The focus of this project is the encapsulation of metal complexes in zeolites and molecular sieves; three applications will be stressed. 1) New zeolites and molecular sieves will be synthesized by means of a recently developed procedure in which the metal complexes act as templates during zeolite crystalli- zation. 2) New catalysts with potential application in catalytic cracking will be prepared by modification of rare earth zeolites with fluorine. These catalysts are much more active in dehydration, dealkylaltion and disproportionation reactions. 3) Zeolite-based magnetic resonance imaging contrast agents will be prepared and optimized. %%% Dr. Kenneth J. Balkus, Jr. of the University of Texas at Dallas is supported as a Presidential Young Investigator by the Inorganic, Bioinorganic, and Organometallic Chemistry Program to study the chemistry of zeolites and molecular sieves. These materials are used in large quantities in industry as drying agents and as catalyst supports. The new materials with encapsulated metals which will be synthesized may have application as catalysts in the petroleum industry and as magnetic resonance imaging (MRI) contrast agents.
