Bimetallic Nanoparticles from Binary Cluster Anions

无机，生物无机和有机化学计划的这一奖项支持马里兰州大学的Bryan Eichhorn教授合成和研究一类新的无配体无机二元簇合物的性质，该簇合物包含催化活性过渡金属和重14族和15族元素。 这些络合物在溶液中的氧化产生在多相催化应用中具有改进的选择性的纳米颗粒。 该研究旨在通过使用活性载体或多组分催化剂颗粒，以及室温合成不同相的合金纳米颗粒来开发具有双功能活性的催化剂。 该项目将研究NOx催化剂的催化过程的化学，包括在富氧废气中的CO氧化和贫NOx还原。 Monoclonal和Monoclonal纳米颗粒用于各种各样的应用，包括光学器件、磁性纳米结构和电子器件。 该研究为多相催化剂的制备提供了分子前体的合成方法。 研究生，本科生和博士后助理将接受合成材料方法学和非均相催化剂研究方面的优秀培训。

This award in the Inorganic, Bioinorganic and Organometallic Chemistry program supports Professor Bryan Eichhorn at the University of Maryland to synthesize and study the properties of a new class of ligand-free inorganic binary clusters comprising catalytically-active transition metals and heavy group 14 and group 15 elements. Oxidation of these complexes in solution yields bimetallic nanoparticles with improved selectivity in heterogeneous catalytic applications. The research aims at developing catalysts with bifunctional activities through the use of active supports or multi-component catalyst particles, and the room temperature synthesis of different phases of alloy nanoparticles. The project will investigate the chemistry of catalytic processes of bimetallic catalysts including those for CO oxidation and lean NOx reduction in O2-rich exhaust gases. Monometallic and bimetallic nanoparticles are used in a wide variety of applications including optical devices, magnetic nanostructures, and electronic devices. This research will provide synthetic methodologies for bimetallic molecular precursors to advance the technology of heterogenous catalysts. Graduate students, undergraduate students and postdoctoral associates will receive excellent training in synthetic materials methodology and the study of bimetallic heterogeneous catalysts.
