主要内容:

Synthetic zeolites are class of porous crystalline aluminosilicate materials with intrinsic pore sizes of <1 nm, being the most important yet practical porous materials in chemical industry. They have been used as solid acid catalysts for many industrial catalytic applications, especially petrochemical industries such as fluidised catalytic cracking (FCC), hydrocracking, hydrocarbon isomerisation and alkylation. However, their intrinsic micropores can cause accessibility/diffusion issues, which reduce the efficiency of their uses in catalysis and cause the catalyst deactivation. The introduction of secondary mesopores (2-50 nm) into the zeolites’ frameworks can help to address the accessibility/diffusion issues, and it can be achieved practically by the post-synthetic treatment methods such as dealumination and desilication. In this seminar, the recent development of new post-synthetic treatment methods in Fan’s group for making mesoporous FAU Y zeolites and mesoporous MFI ZSM-5 nanoboxes (with a very low silicon to aluminum ratio) will be presented, highlighting the novelty of these newly developed methods and the significance of the developed zeolites in catalysis.
