U.S.-Korea Cooperative Research: Chemical and Crystallo- graphic Studies of Silver in Zeolite A

本提案要求资助夏威夷大学化学系Karl Seff博士与釜山国立大学化学系Yang Kim博士进行为期24个月的合作研究项目，以继续对a沸石中银的沸石内化学的合成和结晶学研究。这可能会导致形成新的高对称性星团，将进行尝试。这些团簇结构的晶体学研究将由x射线衍射方法确定。本课题是研究a型沸石中银原子和银离子的合成和结构，以及在沸石大腔内制备银分子配合物的基础研究课题。虽然已知小簇金属原子对各种有机反应具有明显的催化活性，但本项目并不关注银在沸石a .博士中的潜在催化性能。Seff和Kim是备受尊敬的科学家，他们在过去的合作中取得了成功。INT-8316234和INT-8113065。目前的项目将使他们能够继续这种合作。该项目与美韩合作科学项目的目标相关，该项目旨在通过科学信息、思想、技能和技术的交流以及在互利问题上的合作，提高美韩科学家和工程师之间的合作水平。

This proposal requests funds to permit Dr. Karl Seff, Department of Chemistry, University of Hawaii, to pursue with Dr. Yang Kim, Department of Chemistry, Pusan National University, for a period of 24 months, a program of cooperative research to continue the synthetic and crystallographic study of the intrazeolitic chemistry of silver in zeolite A. New conditions for the preparation of silver clusters within the zeolite, which may result in the formation of new clusters of high symmetry, will be tried. The crystallographic study of the structure of these clusters will be determined by x-ray diffraction methods. This is a basic research project dealing with the synthesis and structure of silver atoms and silver ions in zeolite A and the preparation of molecular complexes of this silver within the large cavity of zeolite. While small clusters of metal atoms are known to have pronounced catalytic activity for a variety of organic reactions, this project is not concerned with the potential catalytic properties of silver in zeolite A. Drs. Seff and Kim are highly respected scientists who have collaborated successfully in the past, under NSF Grants No. INT-8316234 and INT-8113065. The present project will allow them to continue this collaboration. This project is relevant to the objectives of the U.S.-Korea Cooperative Science Program which seeks to increase the level of cooperation between U.S. and Korean scientists and engineers through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit.
