Presidential Young Investigator Award: Zeolite and MolecularSieve Chemistry

本项目的重点是金属络合物在沸石和分子筛中的包覆；将重点介绍三个应用。1)以金属络合物为模板剂，在沸石晶化过程中合成新型沸石和分子筛。2)对稀土分子筛进行氟改性，可制备出在催化裂化中具有潜在应用前景的新型催化剂。这些催化剂在脱水、脱烷基化和歧化反应中的活性要高得多。3)沸石类磁共振造影剂的制备和优化。%小肯尼斯·J·巴尔克斯博士。他是美国达拉斯得克萨斯大学的一名年轻的总统研究员，由无机化学、生物无机化学和金属有机化学项目资助，研究沸石和分子筛的化学。这些材料在工业上大量用作干燥剂和催化剂载体。将合成的具有包裹金属的新材料可能在石油工业中用作催化剂，并作为磁共振成像(MRI)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.
