GOALI/SusChem: Fundamentals of Oxygen Electrocatalysis on Mixed Metal Oxyhydroxides for Alkaline Membrane ElectrolysisThe development of clean and sustainable energy sources is critical for the economic and environmental vitality of human civilization. Renewable energy, such as sun and wind power, is intermittent and thus expensive to integrate with traditional energy sources at the capacity needed to power the planet. Scalable, inexpensive energy storage technologies are needed. In this project, Dr. Boettcher (University of Oregon) is collaborating with Dr. Ayers at Proton OnSite (Wallingford, Connecticut) to study catalysts for converting water into hydrogen and oxygen gas using renewable electricity as the input. Hydrogen gas is a sustainable, carbon-free, renewable fuel that can be used to replace fossil fuels. It can be used in fuel cells to regenerate electricity on demand or burned like natural gas, without carbon emission. This research addresses the inefficiency of the oxygen production part of the overall reaction. The team combines fundamental studies of how the oxygen production reaction occurs, with more applied aspects of research within the industry-academic collaboration to test optimized catalysts in commercially-relevant systems. The graduate student working on the project completes an industry internship at Proton OnSite. The Proton OnSite researchers visit the University of Oregon-Eugene. The team conducts outreach activities with local middle school students. These activities engage the students in hands-on energy storage and sustainability laboratory activities on the University of Oregon campus, and introduces university freshman to scientific research through research immersion laboratory courses.With this award from the Chemical Catalysis Program of the Division of Chemistry, Assoc. Professor Shannon Boettcher from the University of Oregon (UO) is: (1) synthesizing new multi-cation (oxy)hydroxide oxygen-evolution catalysts to identify active-site motifs and enhance key performance criteria (intrinsic activity, electrical conductivity, and stability), (2) employing in situ and ex situ scattering, x-ray absorption, and photoelectron spectroscopy techniques to correlate local electronic structure and bonding at iron sites to measured intrinsic activities across different catalysts, and (3) applying the fundamental knowledge obtained to design catalyst architectures that are electronically and ionically wired into efficient and stable alkaline-membrane electrolyzers operating at practical current densities 1 A cm-2. The work is carried out in collaboration with Dr. Kathy Ayers at Proton OnSite (Wallingford, CT) and her team. In support of broader-impacts goals, the project integrates research and education through programs developed by Prof. Boettcher including hands-on middle school outreach events and research-immersion laboratories for UO freshman. The industry-academic partnership is strengthened by UO PhD students completing collaborative internships at Proton OnSite, and through Proton team members visiting the UO.

GOALI/SusChem：用于碱性膜电解的混合金属羟基氧化物的氧电催化基础清洁和可持续能源的发展对于人类文明的经济和环境活力至关重要。太阳能和风能等可再生能源是间歇性的，因此与传统能源整合以提供地球所需的电力的成本很高。需要可扩展、廉价的储能技术。在该项目中，Boettcher 博士（俄勒冈大学）与 Proton OnSite（康涅狄格州沃灵福德）的 Ayers 博士合作，研究使用可再生电力作为输入将水转化为氢气和氧气的催化剂。氢气是一种可持续、无碳、可再生的燃料，可用于替代化石燃料。它可用于燃料电池按需再生电力或像天然气一样燃烧，无碳排放。这项研究解决了整个反应中氧气生产部分的低效率问题。该团队将制氧反应如何发生的基础研究与行业学术合作中更多应用方面的研究结合起来，以在商业相关系统中测试优化的催化剂。从事该项目的研究生在 Proton OnSite 完成了行业实习。 Proton OnSite 研究人员访问俄勒冈大学尤金分校。团队与当地中学生开展外展活动。 这些活动让学生参与俄勒冈大学校园的储能和可持续发展实验室实践活动，并通过研究浸入式实验室课程向大学新生介绍科学研究。获得该奖项的化学系化学催化项目，副教授。俄勒冈大学 (UO) 的 Shannon Boettcher 教授：(1) 合成新型多阳离子（氧）氢氧化物析氧催化剂，以识别活性位点并增强关键性能标准（内在活性、导电性和稳定性） ，（2）采用原位和异位散射、X射线吸收和光电子能谱技术将局部电子结构和铁位点的键合关联起来，以测量不同催化剂的本征活性，以及(3) 应用所获得的基础知识来设计催化剂结构，该结构以电子和离子方式连接到在实际电流密度 1 A cm-2 下运行的高效且稳定的碱膜电解槽中。这项工作是与 Proton OnSite（康涅狄格州沃灵福德）的 Kathy Ayers 博士及其团队合作进行的。为了支持影响更广泛的目标，该项目通过 Boettcher 教授开发的项目将研究和教育结合起来，包括中学实践推广活动和俄勒冈大学新生的沉浸式研究实验室。俄勒冈大学博士生在 Proton OnSite 完成合作实习，以及访问俄勒冈大学的 Proton 团队成员加强了行业与学术伙伴关系。
