EAGER: Synthesis of New Ferrolites: Zeolites Containing an All-Iron Framework The First of a New Family of Transition Metal Based Zeolites?

新材料的开发是固态化学研究的一个重要方面，在固态化学研究中，使用非常高温的液体生长所需新材料的晶体可以导致现有设备的改进和新设备的创造，例如新电池或新的永久磁体。在固体和材料化学的支持下，本研究项目致力于新型沸石的制备，这是一类由硅、铝和氧组成的微孔晶态材料，它们都是自然存在的，并已在工业上大规模合成，以满足它们在催化应用中的广泛需求。该项目详细介绍了一种新型沸石的开发，这种沸石含有铁而不是铝和硅。这些铁基沸石可用作工业催化剂、可持续能源生产的新型磁性材料和钠电池的新型正极材料。为了完成这些任务，本科生、研究生和博士后研究人员正在接受使用最先进的仪器合成和表征这些材料的尖端技术方面的培训。这项研究的教育方面确保了训练有素的男性、女性和未被充分代表的少数族裔能够进入劳动力大军，并满足行业对科学家的需求。以第一个包含全铁骨架的方钠石型沸石为模型，Zur Loye小组开发的流体助熔剂合成方法被应用于合成新型铁基骨架材料，该材料可以影响从简单催化材料到新型磁性材料，再到用于固定式储能的新型钠离子电池等大量研究领域。合成的目标是沸石晶体化学的组成和结构的扩展，特别是通过新的合成路线合成以新的骨架结构结晶的铁氧体。优化的反应条件旨在形成新的铁基骨架，特别是A型和Y型沸石结构，然后研究它们的磁性和离子交换钠的能力，这是固定式钠电池应用的必要要求。由于Fe-O-Fe键的存在，不同的骨架具有很高的磁性，这对结构特有的磁性行为产生了重要的影响。同样，特定的框架结构，具有不同大小的通道，预计将极大地影响钠离子的迁移率，因此，这种优化对于电池应用非常重要。

The development of new materials is an important aspect of solid-state chemistry research, where the use of very high temperature liquids to grow crystals of desired new materials can lead to both the improvement of existing and the creation of new devices, such as new batteries or new permanent magnets. With the support of the Solid State and Materials Chemistry, this research project focuses on the preparation of new types of zeolites, a class of microporous, crystalline materials consisting of silicon, aluminum and oxygen that both occur naturally and are synthesized industrially on a very large scale to satisfy the widespread demand for their use in catalysis applications. This project details the development of a new class of zeolites that contain iron instead of aluminum and silicon. These iron-based zeolites can be utilized as catalysts for industry, as new magnetic materials for sustainable energy creation, and as new cathode materials for sodium batteries. To accomplish these tasks, undergraduates, graduate students and postdoctoral researchers are being trained in cutting-edge techniques for synthesizing and characterizing these materials using state of the art instrumentation. The educational aspect of this research assures that highly trained men, women, and underrepresented minorities can enter the workforce and meet industry's need for scientists.Using the first sodalite-type zeolite containing an all iron framework as a model, the hydroflux synthetic method developed in the zur Loye group is applied to the synthesis of new iron-based framework materials that can impact a large number of research areas ranging from simple catalytic materials, to new magnetic materials, to new sodium ion batteries for stationary power storage. The synthetic objective is the compositional and structural expansion of the crystal chemistry of zeolites, specifically synthesis of ferrolites crystallizing in new framework structures via new synthetic routes. The optimized reaction conditions target the formation of new iron based frameworks, specifically the zeolite A and zeolite Y type structures, that are then investigated for their magnetic behavior and for their ability to ion exchange sodium, a necessary requirement for stationary sodium battery applications. The different frameworks are highly magnetic due to the presence of Fe-O-Fe linkages, which exert an important influence on the structure-specific magnetic behavior. Similarly, the specific framework structure, with different sized channels, is expected to greatly impact the sodium ion mobility and, thus, that optimization is important for battery applications.
