With this Grant Opportunities for Academic Liasons with Industry (GOALI) Award co-funded by the Chemical Catalysis Program of the Division of Chemistry and the Office of Multidisciplinary Activities, Professor Shannon Boettcher from the University of Oregon will (1) study the mechanisms by which three-dimensional (3D) structure and local composition control the oxygen-evolution reaction (OER) activity in Ni hydroxide-based electrocatalysts and (2) identify the key factors affecting performance and durability of optimized Ni hydroxide OER catalysts in prototype alkaline-membrane electrolysis systems operating at practical current densities. The work will be carried out in collaboration with Dr. Kathy Ayers at Proton OnSite (Wallingford, CT). The focus on Ni-based OER catalysts is motivated by recent work in the Boettcher laboratory demonstrating that thin films of Ni-Fe hydroxides with 3D layered structures have higher per-atom activities than other known alkaline OER catalysts including IrO2. The team will also conduct outreach activities with local middle school students during furlough days. The middle school students will engage in hands-on energy storage and sustainability design-challenge activities on the University of Oregon campus. The development of clean and sustainable energy sources is critical for both the economic and environmental vitality of human civilization. Renewable energy sources such as the sun and wind are intermittent and thus currently difficult and expensive to integrate with traditional energy sources in large amounts. One promising method to store intermittent renewable energy is by splitting water into hydrogen and oxygen gas. The hydrogen gas can be used as a sustainable carbon-free renewable fuel to replace fossil fuels. This research addresses an important challenge in designing water-splitting systems - the inefficiency of the oxygen production part of the reaction.

凭借该化学分工和多学科活动的化学催化计划与行业（目标）奖的学术机会，俄勒冈大学的Shannon Boettcher教授（1）将研究三维（3D）的结构（3D）结构（3D）结构（3D）结构（3D）的结构（OXYGEN-EVEN-EVERTOS）2 2 2 2 2）确定影响在碱性 - 膜膜电解系统上以实用电流密度运行的原型碱性 - 膜电解系统中优化Ni氢氧化物OER催化剂的性能和耐用性的关键因素。这项工作将与Proton Onite（CT Wallingford）的Kathy Ayers博士合作进行。对基于NI的OER催化剂的关注是由Boettcher实验室的最新工作激发的，这表明具有3D层结构的Ni-Fe氢氧化物的薄膜比包括IRO2在内的其他已知的碱性OER催化剂具有更高的每种原子活性。该团队还将在休假期间与当地中学生进行外展活动。中学生将在俄勒冈大学校园进行动手存储和可持续性设计挑战活动。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。可再生能源（例如太阳和风）是间歇性的，因此与传统能源大量融合的目前很难且昂贵。存储间歇性可再生能源的一种有希望的方法是将水分成氢和氧气。氢气可用作可持续的无碳可再生燃料来代替化石燃料。这项研究解决了设计水分系统的重要挑战 - 反应的氧生产部分的效率低下。
