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.

借助由化学系化学催化项目和多学科活动办公室共同资助的学术与工业联系机会 (GOALI) 奖，俄勒冈大学的 Shannon Boettcher 教授将 (1) 研究三维 (3D) 结构和局部成分控制氢氧化镍基电催化剂中析氧反应 (OER) 活性的机制，以及 (2) 确定影响在实际电流密度下运行的原型碱膜电解系统中优化的氢氧化镍 OER 催化剂性能和耐久性的关键因素。这项工作将与 Proton OnSite（康涅狄格州沃灵福德）的 Kathy Ayers 博士合作进行。 Boettcher 实验室最近的工作表明，具有 3D 层状结构的 Ni-Fe 氢氧化物薄膜比其他已知的碱性 OER 催化剂（包括 IrO2）具有更高的每原子活性，从而激发了对镍基 OER 催化剂的关注。该团队还将在休假期间与当地中学生开展外展活动。中学生将在俄勒冈大学校园参与储能和可持续设计挑战活动。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。太阳能和风能等可再生能源是间歇性的，因此目前与传统能源的大量整合非常困难且昂贵。一种有前途的存储间歇性可再生能源的方法是将水分解成氢气和氧气。氢气可作为可持续的无碳可再生燃料来替代化石燃料。这项研究解决了水分解系统设计中的一个重要挑战——反应中氧气生产部分的低效率。
