U.S.-Polish Cooperative Research on Activation of Small Molecules on Polyoxometalate Surfaces

9414097 Pope乔治敦大学的Michael T.Pope博士和西里西亚大学的Krzysztof Filipek博士就“多金属氧酸盐表面小分子的活化”开展了这项美国-波兰联合合作研究。这项拟议的合作与波普博士目前的美国国家科学基金会拨款CHE-9215228“大的多金属氧酸盐阴离子的表面反应性的调制”有关。具体地说，主要研究人员打算探索和/或开发在水和非水溶剂中通过适当修饰的多金属氧酸盐阴离子激活小分子(例如，NO、NO2、CO2、SO2、O2)。乔治敦大学和其他地方的早期研究已经证明了NO、O2、SO2和CO2与多金属氧酸盐的结合。Filipek博士最近的研究重点是氮和氮氧化物与含Ru的多金属氧酸盐的结合和多电子还原。这与乔治敦大学在多金属氧酸盐的氧化还原化学和钨酸盐的表征方面发展的经验密切相关。多金属氧酸盐可逆地接受两个、四个或更多电子的能力表明，可能存在将还原等价物引导到结合的“底物”的途径。：很明显，由于利益的强烈重叠，两个研究项目都将从合作中受益。多金属氧酸盐化学的这项拟议研究通过使美国和波兰的顶尖专家能够在相互感兴趣和能力很强的领域结合互补的人才和汇集研究资源来实现推进科学的计划目标。*

9414097 Pope This U.S.-Polish Joint Cooperative Research on "Activation of Small Molecules on Polyoxometalate Surfaces" is between Dr. Michael T. Pope of Georgetown University and Dr. Krzysztof Filipek of the University of Silesia. The proposed collaboration is related to Dr. Pope's current NSF grant, CHE- 9215228, "Modulation of Surface Reactivity of Large Polyoxometalate Anions." Specifically, the principal investigators intend to explore and/or develop the activation of small molecules (e.g., NO, NO2, CO2, SO2, O2) by appropriately modified polyoxometalate anions in aqueous and non-aqueous solvents. The binding of NO, O2, SO2, and CO2 to polyoxometalates has already been demonstrated in earlier work from Georgetown and elsewhere. The focus of Dr. Filipek's recent research has been on the binding and multi-electron reduction of dinitrogen and nitrogen oxides with ruthenium-containing polyoxometalates. this ties in closely with the experience developed at Georgetown regarding the redox chemistry of polyoxometalates, and the characterization of tungstoruthenates. The ability of polyoxometalates reversibly to accept two, four, or more electrons suggests that pathways could exist for channelling reduction equivalents to the bound "substrates.: It is clear because of the strong overlap in interests, both research programs will benefit from the collaboration. This proposed research in polyoxometalate chemistry fulfills the program objectives of advancing science by enabling leading experts in the U.S. and Poland to combine complementary talents and pool research resources in areas of strong mutual interest and competence. ***
