TOPIC
▸　Critical Factors for Regulating the Crystallization of Zeolites

Abstract
❝　Zeolites are crystalline aluminosilicates possessing well-defined micropores and channels, which are widely used in industry as ion-exchangers, molecular sieves, and catalysts. For example, zeolites are vital catalysts for fluid catalytic cracking (FCC) in the oil refinery industry, while these materials also play a crucial role in methanol-to-hydrocarbon (MTH) conversion, nitrogen oxides (NOx) reduction, and CO2 capture. However, the efficient synthesis of zeolites with desired physicochemical properties remains challenging, mainly due to the insufficient understanding of their crystallization mechanisms, hence lacking strategies to control their crystallization behaviors.
❝　In this talk, I will show how synthesis conditions can influence the crystallization of zeolite X (FAU-type), which is one of the most common types of zeolites used in chemical industry. Based on an array of time-resolved characterizations, such as synchrotron X-ray total scattering and spectroscopic measurement, we revealed critical factors that promote the formation of zeolite X.　❞
