There is a strong need for high performance catalysts in energy-related technologies such as fuel cells and batteries to meet the growing energy demands across the globe and reduce dependence on fossil fuels. Catalysts in energy storage and conversion devices promote the key electrochemical reactions that determine their efficiency, durability and cost. Most of these applications require that the catalysts have large surface area paired with suitable chemistry to facilitate the reaction kinetics. Despite progress at various levels, a versatile nanomanufacturing technology that can meet the necessary requirements of high catalytic activity, durability and cost effectiveness is lacking. This award will investigate a new paradigm of metallic nanostructure catalysts for use in a number of energy conversion and storage applications. Together with the basic research, an education program will be developed to provide training and research opportunities to graduate students, undergraduates, and high school students. Special efforts will be made to encourage women and under-represented minority students to participate in the research, which will improve their retention in science and engineering. The concept, theory, and results will be used in strengthening existing and creating new undergraduate and graduate level courses. The success of this project will provide a transformative approach for scalable nanomanufacturing of metallic-glass catalysts for clean energy conversion and storage technologies such as fuel cells, batteries, and water splitting systems.The objectives of this research are to study fundamental mechanisms of catalytic activity for metallic glass nanostructures, and to create scalable and low-cost approaches for nanomanufacturing high-performance amorphous catalysts for energy conversion and storage technologies. Metallic-glasses are attractive as high-performance electrocatalysts because of their metastable structure, tunable chemistry, and availability in a wide range of compositions. Despite these unique attributes, the application of metallic glasses has been impeded by the limited ability to produce high-quality catalysts. This research will develop a novel process that directly transforms conventional metals into high-performance hierarchical nanocatalysts. In addition, simulations of the metallic-glass surface morphology and chemistry and their effect on catalytic activity will be carried out using first-principles methods. The integration of experiment and computation to determine electro-catalytic activity will speed up the search for the best metallic glass catalysts, provide better understanding of the catalytic phenomena, and uncover new reaction mechanisms.

燃料电池和蓄电池等能源相关技术迫切需要高性能催化剂，以满足全球不断增长的能源需求并减少对化石燃料的依赖。能量存储和转换设备中的催化剂促进决定其效率、耐用性和成本的关键电化学反应。大多数这些应用要求催化剂具有大的表面积以及合适的化学性质以促进反应动力学。尽管在各个层面取得了进展，但仍缺乏一种能够满足高催化活性、耐用性和成本效益的必要要求的通用纳米制造技术。该奖项将研究用于多种能源转换和存储应用的金属纳米结构催化剂的新范例。在基础研究的同时，还将制定教育计划，为研究生、本科生和高中生提供培训和研究机会。我们将特别努力鼓励女性和代表性不足的少数族裔学生参与研究，这将提高他们在科学和工程领域的保留率。这些概念、理论和结果将用于加强现有的和创建新的本科生和研究生水平课程。该项目的成功将为用于清洁能源转换和存储技术（例如燃料电池、电池和水分解系统）的金属玻璃催化剂的可扩展纳米制造提供变革性方法。本研究的目的是研究金属玻璃纳米结构催化活性的基本机制，并为用于能量转换的高性能非晶态催化剂纳米制造创建可扩展且低成本的方法 和存储技术。金属玻璃作为高性能电催化剂具有吸引力，因为它们具有亚稳态结构、可调节的化学性质以及多种成分的可用性。尽管具有这些独特的属性，但金属玻璃的应用因生产高质量催化剂的能力有限而受到阻碍。这项研究将开发一种新工艺，直接将传统金属转化为高性能分级纳米催化剂。此外，将使用第一原理方法对金属玻璃表面形态和化学及其对催化活性的影响进行模拟。结合实验和计算来确定电催化活性将加快寻找最佳金属玻璃催化剂的速度，更好地理解催化现象，并揭示新的反应机制。
