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.

新材料的开发是固态化学研究的一个重要方面，在该方面，使用非常高温的液体来种植所需的新材料的晶体可以导致现有和创建新设备的改善，例如新电池或新的永久磁铁。 在固态和材料化学的支持下，该研究项目的重点是制备新型的沸石，这是一类由硅，铝和氧气组成的微孔，晶体材料，它们都是自然发生的，并且在工业上进行了非常大规模的工业合成，以满足其在催化应用中的广泛需求。该项目详细介绍了一类新的沸石的开发，这些沸石含有铁，而不是铝和硅。 这些基于铁的沸石可以用作工业的催化剂，作为可持续能源创造的新磁性材料，以及用于钠电池的新的阴极材料。为了完成这些任务，正在对本科生，研究生和博士后研究人员进行培训，以使用最先进的技术来合成和表征这些材料，以使用最先进的仪器来综合和表征这些材料。 这项研究的教育方面确保了高度训练有素的男性，女性和人为少数群体可以进入劳动力并满足行业对科学家的需求。使用第一个包含所有铁框架作为模型的Sodalite-type Zeolite，在Zur Loye组中开发的HydroFlux合成方法，可以将ZUR LOYE型材料应用于新的Iral Iral Irally Inderthess，从而影响了新的Irallux Groute，这可以影响新的Iral Iral Inlate Inderthess，从而影响了新的Iral Iral Inrol Inserthis，该材料的构成量很大材料，新的磁性材料，到新的钠离子电池，用于固定电源存储。 合成目标是沸石的晶体化学的组成和结构膨胀，特别是通过新的合成途径在新的框架结构中结晶的铁岩的合成。 优化的反应条件针对新的基于铁的框架的形成，特别是沸石A和沸石Y型结构，然后研究其磁性行为以及其离子交换钠的能力，这是固定钠电池应用的必要要求。 由于存在Fe-O-FE连接，因此不同的框架具有极高的磁性，这对结构特异性磁性行为产生了重要影响。 同样，具有不同大小通道的特定框架结构有望极大地影响钠离子的迁移率，因此，优化对于电池应用很重要。
