Case Study

Aluminum Ethoxide Used for the Preparation of ZSM-5 Zeolite with Controlled Aluminum Distribution for Catalytic Applications

Wang, Yilin, et al. Microporous and Mesoporous Materials 351 (2023): 112491.

Aluminum ethoxide (Al(EtO)₃) plays a pivotal role in the synthesis of ZSM-5 zeolites, which are highly valued in catalytic applications due to their controlled porous structure and acidic properties. In this study, aluminum ethoxide is used as an aluminum source to prepare ZSM-5 zeolite with a specific arrangement of aluminum sites, affecting its catalytic activity.
The synthesis begins by preparing a precursor gel with a molar composition of SiO₂:0.03Al:0.2TPAOH:15H₂O:20Toluene. Aluminum ethoxide is dissolved in toluene and mixed with other organic aluminum agents, including aluminum nitrate nonahydrate, aluminum isopropoxide, and aluminum sec-butoxide. The silica source, Ludox HS-40, is mixed with TPAOH in water to form a homogeneous aqueous solution. After combining the oil and aqueous phases, the gel undergoes crystallization in an autoclave at 453 K for 48 hours, followed by centrifugation, washing, and drying. The obtained solid is calcined at 833 K to yield H-form ZSM-5 zeolite, which is designated as ZSM-5-E when aluminum ethoxide is used.
This approach demonstrates the significant influence of aluminum ethoxide on the aluminum distribution within the zeolite framework, affecting the final catalytic properties. The resulting ZSM-5 zeolites can be utilized in various catalytic processes, including hydrocracking and isomerization.

Aluminum Ethoxide Used for the Synthesis of Al-PEG Prepolymer for Artificial Solid Electrolyte Interphase (ASEI) Films

Li, Dandan, et al. Journal of Power Sources 563 (2023): 232808.

Aluminum ethoxide (Al(EtO)₃) plays a crucial role in the synthesis of Al-PEG prepolymers for the development of artificial solid electrolyte interphase (ASEI) films, which are vital in preventing dendrite growth in lithium metal batteries. The Al-PEG prepolymer is synthesized via an alcoholysis reaction, where aluminum ethoxide reacts with polyethylene glycol (PEG) and methoxy polyethylene glycol (MPEG) in the presence of p-xylene at elevated temperatures under an argon atmosphere.
In this method, aluminum ethoxide (0.1620 g) is dissolved in p-xylene and reacts with MPEG and PEG in a 1:1 ratio at 80 °C for 12 hours. The solvent is then removed by reduced pressure distillation, resulting in a yellow viscous liquid that forms the Al-PEG prepolymer. This prepolymer is subsequently crosslinked with the trimer of hexamethylene diisocyanate (THDI) to form a robust ASEI film with tunable mechanical properties.
These ASEI films are deposited onto lithium metal electrodes, offering high mechanical strength and providing a stable interface between the electrode and electrolyte. The use of aluminum ethoxide in the synthesis of Al-PEG prepolymers is a key step in producing advanced materials for improving the performance and safety of lithium metal batteries.
