Study on ZSM-5 zeolite-encapsulated Pt and its application in catalysis

Metal nanoparticles have drawn much attention during the last few years due to their unique properties, particularly their high catalytic activity in many reactions. Catalytic activity increases when the particle size decreases, thus the most active catalysts are below 5 nm in size. The objective of this project is to investigate the catalytic performance for the alkylation of benzene with methanol and hydrogenation of nitrobenzene and nitronaphthalene of a hierarchical porous Pt@ZSM-5 catalyst. In this catalyst, Pt nanoparticles are confined into the pores and cavities of the zeolite. This catalyst was synthesized by a dry-gel conversion in-situ synthesis method. The end goal is to obtain the most selective and stable catalytic reaction performance. This is done by testing the catalyst’s performance at different structural and textural properties. The varying properties of the catalysts are systematically characterized and implemented by wet impregnation techniques. TO BE CONT’D
