Bimetallic Nanoparticles from Binary Cluster Anions

这个无机、生物无机和有机金属化学项目的奖项支持马里兰大学的Bryan Eichhorn教授合成和研究一类新的无配体无机二元簇的性质，该簇由催化活性过渡金属和14族和15族重元素组成。这些配合物在溶液中氧化产生双金属纳米颗粒，在非均相催化应用中具有更好的选择性。本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，开发具有双功能活性的催化剂。该项目将研究双金属催化剂催化过程的化学性质，包括在富含o2的废气中氧化CO和减少贫氮氧化物的化学过程。单金属和双金属纳米颗粒广泛应用于光学器件、磁性纳米结构和电子器件等领域。本研究将为双金属分子前驱体的合成提供新的方法，推动多相催化剂技术的发展。研究生、本科生和博士后将接受合成材料方法学和双金属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.
