Solid catalysts play an important role in energy-efficient commercial processes used to produce fuels, chemicals, and energy, and also in pollution mitigation. Most commercial solid catalysts used today consist of metal particles supported on high surface area support materials. Improvements in these catalysts are needed to further improve their efficiency. Successful research in this area results in lower energy consumption and reduced environmental impact of many chemical processes. One approach to this goal is through control of the interfaces between the metal particles and the support materials. In this project, Dr. Nikolla (Wayne State University) and Dr. Medlin (University of Colorado) are developing an understanding these metal/support interfaces with the objective of discovering more active and efficient catalysts. Dr. Nikolla and Dr. Medlin actively engage in outreach activities related to the education of young students, especially those from underrepresented groups. For example, they are developing workshops for underrepresented K-12 female students to enhance their understanding and desire in pursuing higher education in science, technology, engineering, and mathematics (STEM) fields. Dr. Nikolla and Dr. Medlin are also designing activities to inform parents about STEM fields, so that the parents can encourage their children to pursue STEM education.With funding from the Chemical Catalysis Program of the Chemistry Division, Dr. Eranda Nikolla of Wayne State University and Dr. Will Medlin of University of Colorado are developing an understanding of solid metal/metal oxide interfaces in "inverted" catalytic systems with the objective of enhancing catalytic activity and selectivity in chemical reactions. They are synthesizing controlled metal oxide-encapsulated metal nanoparticles (i.e., M@MO structures) with systematic variations in structure and composition of both the metal and metal oxide components. The research team correlates these synthetic variations to the surface chemical properties and catalyst performance. Fundamental insights from experimental model catalysts coupled with advanced characterization and computational studies on inverted catalyst systems are being used to advance the understanding of interfacial chemistry. The encapsulated catalyst systems are also being investigated as a platform for controlling the near-surface environment around the reactive interface through functionalization of the oxide pores with organic ligands. Dr. Nikolla and Dr. Medlin are actively engaged with educational and research outreach activities aimed at inspiring and informing undergraduate and K-12 female students from underrepresented groups regarding STEM fields and research in the area of catalysis.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

固体催化剂在用于生产燃料，化学物质和能量的能源效率的商业过程中起着重要作用，并且在减轻污染方面也起着重要作用。当今使用的大多数商用固体催化剂由高表面积支撑材料支撑的金属颗粒组成。需要改善这些催化剂以进一步提高其效率。该领域的成功研究导致能源消耗降低，并减少许多化学过程的环境影响。实现此目标的一种方法是控制金属颗粒和支撑材料之间的界面。在该项目中，尼科拉（Wayne State University）博士和梅德林（Medlin）博士（科罗拉多大学）正在发展理解这些金属/支撑界面，目的是发现更积极，有效的催化剂。 Nikolla博士和Medlin博士积极从事与年轻学生的教育有关的外展活动，尤其是来自代表性不足的学生的教育。例如，他们正在为代表性不足的K-12女学生开展研讨会，以增强她们在进行科学，技术，工程和数学（STEM）领域的高等教育方面的理解和渴望。 Nikolla博士和Medlin博士也在设计活动，以告知父母STEM领域，以便父母可以鼓励他们的孩子接受STEM教育。从化学分部的化学催化计划中获得资金，Wayne State的Eranda Nikolla博士大学和科罗拉多大学的威尔·梅德林（Will Medlin）正在对“倒”催化系统中的固体金属/金属氧化物界面的理解，目的是增强化学反应中的催化活性和选择性。它们正在合成具有系统变化的金属纳米颗粒（即M@MO结构），并具有系统的结构和金属氧化物组件的组成和组成。 研究小组将这些合成变化与表面化学特性和催化剂性能相关联。实验模型催化剂的基本见解，加上高级表征和倒催化剂系统的计算研究，以促进对界面化学的理解。还研究了封装的催化剂系统，作为通过有机配体的氧化物孔功能化来控制反应性界面周围近地面环境的平台。 Nikolla博士和Medlin博士积极参与旨在启发和告知本科生和K-12女学生的教育和研究宣传活动使用基金会的知识分子优点和更广泛的审查标准，被认为值得通过评估来支持。
