This award from the Major Research Instrumentation (MRI) program enables the study of important electrochemical reaction mechanisms, such as, carbon dioxide electrochemical conversion and electrochemical hydrogenation of unsaturated biofuels on emerging nanocatalysts. In combination with advanced gas chromatography system, this instrument strengthens the product analysis facility at a minority-serving institution, Elizabeth City State University (ECSU). It also supports both research training and education of underrepresented minority students at ECSU in state-of-the-art research areas such as electrochemistry, nanocatalysts and renewable energy storage systems. This system facilitates several research projects with both domestic and international collaborators. Regionally, two faculty members and numerous students from Old Dominion University (ODU) and Eastern Carolina University (ECU) working on collaborative projects will directly benefit from this facility. The award supports the acquisition of a Differential Electrochemical Mass Spectrometry (DEMS) system consisting of microflow capillary inlets for research and education at ECSU. The real time electrochemical reaction intermediates and products analysis by DEMS is at the center of identifying reaction mechanism of several electrochemical reactions and providing fundamental knowledge for the development of efficient nanocatalysts. In one project, research focuses on understanding of carbon dioxide electrochemical reduction mechanism on grain-boundaries or edge atoms of two-dimensional transition metal dichalcogenide nanosheets. This project further enables the development of an efficient catalytic system consisting of heterogeneous grain-boundaries for efficient carbon dioxide conversion into valuable products. In another project with ODU, this instrument addresses the question of how electrochemical hydrogenation occurs on reduced metal oxide nanostructures to help designing more energy-efficient and cost-effective catalytic system for conversion of bio-oils into transportation fuels. The gained knowledge will broadly benefit areas related to nanocatalysts, renewable energy storage systems and biofuel production.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.

来自主要研究仪器（MRI）计划的这一奖项使重要的电化学反应机制的研究成为可能，例如二氧化碳电化学转化和新兴纳米催化剂上不饱和生物燃料的电化学氢化。该仪器与先进的气相色谱系统相结合，加强了为少数民族服务的机构伊丽莎白城州立大学（ECSU）的产品分析设施。 它还支持ECSU在最先进的研究领域（如电化学，纳米催化剂和可再生能源存储系统）中代表性不足的少数民族学生的研究培训和教育。该系统促进了国内和国际合作者的几个研究项目。在区域范围内，两名教师和许多学生从旧自治领大学（ODU）和东卡罗莱纳大学（ECU）的合作项目工作将直接受益于这一设施。该奖项支持在ECSU收购由微流毛细管入口组成的差示电化学质谱（DEMS）系统，用于研究和教育。 利用DEMS对电化学反应中间体和产物进行真实的实时分析，是确定多种电化学反应机理的核心，也是开发高效纳米催化剂的基础知识。在一个项目中，研究重点是理解二维过渡金属二硫属化物纳米片的晶界或边缘原子上的二氧化碳电化学还原机制。该项目进一步开发了一种由异质晶界组成的高效催化系统，用于将二氧化碳有效转化为有价值的产品。在与ODU合作的另一个项目中，该仪器解决了电化学氢化如何在还原的金属氧化物纳米结构上发生的问题，以帮助设计更节能和更具成本效益的催化系统，将生物油转化为运输燃料。 该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
