项目摘要
The development of clean and sustainable energy sources is critical for the economic and environmental vitality of human civilization. Renewables, such as sun and wind power, are intermittent and thus expensive to integrate with fossil fuels 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 / Nel Hydrogen (Wallingford, Connecticut) to study the conversion of water (H2O) into hydrogen (H2) and oxygen (O2) gas using renewable electricity as the input. Hydrogen gas is a sustainable, carbon-free, renewable fuel to replace fossil fuels. It can be used in fuel cells to re-generate electricity on demand or burned like natural gas, without carbon dioxide emission. This research is addressing the inefficiency of the oxygen production part of the overall reaction. The team combines fundamental studies to understand how this reaction occurs and how to improve it. The industry-academic collaboration is testing the findings in commercially-relevant systems. In one example, the team is studying how chemical species containing iron, when placed in different environments, speed up the generation of oxygen and save energy in making hydrogen. The team is working to understand how these iron species change under long-term practical operating conditions. The team is also designing new materials that work well with existing technology but are less expensive to manufacture. The graduate students working on the project complete industry internships at Proton OnSite. The team conducts outreach activities with local middle school students that engages them in hands-on energy storage and sustainability laboratory activities on the University of Oregon campus, and introduces first year university students to scientific research through research-immersion courses. Funding for this award is provided by the Chemical Catalysis Program in the Division of Chemistry and the Catalysis Program in Chemical, Bioengineering, Environmental and Transport Systems. Professor Shannon Boettcher from the University of Oregon (UO) is collaborating with Dr. Kathy Ayers at Proton OnSite / Nel Hydrogen (Wallingford, CT) and her team to use well-controlled electrochemical synthesis to create Fe in different local environments in transition-metal oxyhydroxide and oxide phases and probe OER mechanism and activity/durability relationships using a host of advanced operando techniques. They uncover the compositional, structural, and morphological dynamics that drive performance degradation in (oxy)hydroxide/oxide OER catalysts under long-durations and high-current densities. The team also creates new synthetic approaches to assemble precious-metal OER catalysts for use in proton-exchange-membrane electrolyzers where every precious metal atom is available to drive the OER while chemically stabilized by appropriate oxo linkages to inactive metal cations and through support interactions. This research has the potential to decouple the apparent inverse relationship observed between stability and activity for OER catalysts while connecting industry and academic researchers through graduate-student internships at Nel Hydrogen / Proton Onsite and industry researcher visits to Oregon. These science aims are coupled with outreach and education activities. Graduate students lead teams of undergraduates through a “research-immersion” course developed by Boettcher that enables first-year chemistry students to earn credit for general chemistry laboratory by working on real, unsolved scientific questions. Hands-on middle school outreach events in the area of energy and electrochemistry are available to underserved students through an ongoing program founded by Boettcher. Funding for this award is provided by the Chemical Catalysis Program in the Division of Chemistry and the Catalysis Program in Chemical, Bioengineering, Environmental and Transport Systems.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.
开发清洁和可持续能源对人类文明的经济和环境活力至关重要。可再生能源,如太阳能和风能,是间歇性的,因此与化石燃料结合为地球提供动力所需的能力是昂贵的。需要可扩展的、廉价的储能技术。在这个项目中,Boettcher博士(俄勒冈州大学)正在与Proton OnSite / Nel Hydrogen(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(H2O)转化为氢气(H2)和氧气(O2)。氢气是一种可持续、无碳、可再生的燃料,可替代化石燃料。它可用于燃料电池,按需再生电力或像天然气一样燃烧,而不会排放二氧化碳。这项研究正在解决整个反应中氧气生产部分的效率低下问题。该团队结合基础研究来了解这种反应是如何发生的以及如何改善它。业界和学术界的合作正在商业相关系统中测试这些发现。在一个例子中,该团队正在研究含铁的化学物质如何在不同的环境中加速氧气的产生并节省制氢的能量。该团队正在努力了解这些铁物种在长期实际操作条件下如何变化。该团队还在设计新材料,这些材料与现有技术配合良好,但制造成本较低。参与该项目的研究生在Proton OnSite完成行业实习。该团队与当地中学生开展外展活动,让他们在俄勒冈州大学校园内参与储能和可持续性实验室活动,并通过研究浸入式课程向大学一年级学生介绍科学研究。该奖项的资金由化学部的化学催化计划和化学,生物工程,环境和运输系统的催化计划提供。来自俄勒冈州大学(UO)的Shannon Boettcher教授正在与Proton OnSite / Nel Hydrogen(Wallingford,CT)的Kathy Ayers博士及其团队合作,使用良好控制的电化学合成在不同的局部环境中以过渡金属氢氧化物和氧化物相产生Fe,并使用大量先进的操作技术探测OER机制和活性/耐久性关系。 他们揭示了在长时间和高电流密度下驱动(氧)氢氧化物/氧化物OER催化剂性能退化的组成,结构和形态动力学。 该团队还创建了新的合成方法来组装用于质子交换膜电解槽的贵金属OER催化剂,其中每个贵金属原子都可用于驱动OER,同时通过适当的氧代键与非活性金属阳离子和通过支持相互作用进行化学稳定。这项研究有可能解耦OER催化剂的稳定性和活性之间观察到的明显的反比关系,同时通过Nel Hydrogen / Proton Onsite的研究生实习和行业研究人员访问俄勒冈州来连接行业和学术研究人员。这些科学目标与推广和教育活动相结合。 研究生带领本科生团队通过Boettcher开发的“沉浸式研究”课程,使一年级的化学学生通过研究真实的未解决的科学问题来获得普通化学实验室的学分。 在能源和电化学领域的动手中学外展活动可通过Boettcher创办的一个正在进行的计划提供给服务不足的学生。该奖项的资金由化学部的化学催化计划和化学、生物工程、环境和运输系统的催化计划提供。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。
