112	Synthesis of Mesoporous Palladium Nanoparticles and Its Application in Heck Reaction Li, Jheng-Guang 20 January 2009 (has links) In our study, 3D interconnection channels of mesoporous silica MCM-48 was used as template. We try to fill the channels with the metal precussor by ¡§incipient wetness¡¨ technique. After the reduction with H2, the composites containning metal Pd and MCM-48 could be obtained. Then, Pd nanowire network was obtained through HF etching. The mesoporous palladium nanoparticles are obtained and we try to use it as the catalyst in the Heck coupling reaction of £\-methylstyrene and p-bromoacetophenone. We find that our catalyst have different effect in this Heck reaction. The terminal and internal (E/Z form) isomer ratio variated in the reaction. In the future, we will attempt to apply our mesoporous Palladium nanoparticles as organic molecule storage. The MCM-48 and mesoporous Palladium nanoparticles were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), scanning electron microscopy (SEM) and high-resolution nitrogen adsorption.We used NMR and GC to trace the reaction. Heck reaction was performed as a test reaction to compare catalytic performances of the meosoporous Palladium nanoparticles and the catalyst of refrence. mesoporous Heck reaction Palladium
