Spectroscopic Studies of Supported Iron Carbidocarbonyl Clusters (Engineering)

将对负载铁羰基簇进行IR和SS-NMR研究。本研究将负载型金属催化剂化学领域的专业知识与有机金属化学和均相催化领域的专业知识相结合。借用表面化学技术，金属团簇将被锚定在支撑物上，为它们提供更类似于通常发现的多相催化剂的环境。在这种环境下，金属团簇将受到热和化学处理，同时监测配体和金属框架的转变。将努力探索支持团簇系统的分子化学，并将观察结果与已知的非支持团簇的溶液化学和相关吸附-金属表面系统的不太明确的表面化学进行比较。这些研究将通过这些相互作用提供对集群系统结构的理解，从而有可能发展对广泛的金属-有机相互作用的基本理解，这可能为金属表面上类似的相互作用提供宝贵的线索。互动活动包括为女本科生举办的研讨会，题为“化学工程的研究生教育”。这项活动将有助于鼓励年轻女性考虑从事科学研究。此外，还将教授一门关于催化主题的研究生课程。该项目进一步推进了VPW计划的目标，即(1)为女性提供在工程和NSF支持的科学学科中发展职业的机会；(2)通过为在工业、政府和学术机构工作的女性科学家和工程师提供更大的知名度，鼓励女性在科学和工程领域追求职业。通过鼓励妇女参与科学，这是对国家未来科学活力的宝贵投资。

IR and SS-NMR studies of supported iron carbidocarbonyl clusters will be conducted. This research combines expertise developed in the field of supported metal catalyst chemistry with that of organometallic chemistry and homogeneous catalysis. Borrowing from surface chemistry techniques, metal clusters will be anchored to supports to provide them with an environment more similar to that of a heterogeneous catalyst is usually found. In this environment, the metal cluster will be subjected to thermal and chemical treatments while monitoring the transformations that the ligands and the metal framework undergo. An effort will be made to probe the molecular chemistry of the supported cluster system and compare the observations with the known solution chemistry of the unsupported cluster and the less-well-defined surface chemistry of related adsorbate-metal surface systems. The studies will provide an understanding of the structure of the cluster systems throughout these interactions, giving the potential to develop a fundamental understanding of a wide range of metal-organic interactions that may provide invaluable clues concerning similar interactions on metal surfaces. Interactive activities include a workshop for women undergraduates entitled, "Graduate Education in Chemical Engineering." This activity will help encourage young women to consider careers in scientific research. In addition, a graduate course on topics in catalysis will be taught. This project furthers VPW program objectives which are (1) to provide opportunities for women to advance their careers in engineering and in the disciplines of science supported by NSF and (2) to encourage women to pursue careers in science and engineering by providing greater visibility for women scientists and engineers employed in industry, government, and academic institutions. By encouraging the participation of women in science, it is a valuable investment in the Nation's future scientific vitality.
