In this CAREER award, funded by the Chemical Structure, Dynamics and Mechanisms (CSDM-A) Program of the Division of Chemistry, Professor Anastassia Alexandrova of the University of California - Los Angeles and her team are investigating the potential of sub-nano-sized clusters of platinum and palladium clusters, doped with other atoms, to be used as catalysts in chemical reactions. Catalysis is important to the chemical industry in providing efficient, low-energy methods for chemical synthesis. The young researchers working on this project will receive in-depth training in state-of-the art computational methods.Professor Alexandrova and her research group will use first-principle calculations and multi-scale methods to probe the chemical bonding and reactivity in small transition metal clusters, both free and bound to surfaces. The results from this project will help develop a better understanding of any reactivity rules for these small clusters, guiding work of experimentalists in developing improved catalysts. Computational results for gas-phase clusters will be compared with experimental results. The computational methods should find applications in other condensed-phase systems.

在这项由化学系化学结构、动力学和机理(CSDM-A)计划资助的职业奖项中，加州大学洛杉矶分校的Anastassia Alexandrova教授和她的团队正在研究亚纳米尺寸的铂和钯原子团簇在化学反应中用作催化剂的潜力。在为化学合成提供高效、低能耗的方法方面，催化对化学工业很重要。从事这个项目的年轻研究人员将接受最先进的计算方法的深入培训。Alexandrova教授和她的研究小组将使用第一性原理计算和多尺度方法来探索小过渡金属团簇中的化学键和反应性，无论是自由的还是束缚在表面的。这个项目的结果将有助于更好地理解这些小团簇的任何反应性规则，指导实验者开发改进的催化剂的工作。气相团簇的计算结果将与实验结果进行比较。这些计算方法应该在其他凝聚相系统中得到应用。
