Preparation And Catalytic Properties Of New Organic Mesoporous Materials Supported Metal Catalysts

With the requirement of sustainable development, chemical process of innocuity is becoming increasingly important, more and more environmentally friendly catalysts are widely used. Heterogeneous catalysts can realize repeat recycling, according with green chemistry requirements.This thesis mainly consists of two parts. The first part mainly introduces new heterogeneous FDU mesoporous material supported Palladium catalysts including preparation, characterization and application in Sonogashira cross coupling reaction. Palladium catalyst is one of the most important metal catalysts. The traditional Palladium catalysts need phosphorus ligands and the CuI as cocatalysts in Sonogashira cross coupling reaction. Traditional methods need hard reaction conditions which cause byproduct and metal residue in product and easily lead to the environment pollution. This paper introduces new heterogeneous metal catalysts, which have FDU as supporting, can achieve Sonogashira cross coupling reaction without copper and phosphorus conditions. This reaction is higher catalytic activity in mild reaction condition, wider universality to the substrate, easier being separated and better at recycling. The catalysts are characterized by the XRD, N2-sorption, TEM, finding them keeping good structure after functionalization.The second part is mainly about amine functionalized FDU mesoporous material supported metal catalyst and its application. Firstly, the amine functionalized FDU interacting chlorine gold acid through electrostatic ions, then reducting by sodium borohydride reagent for preparation loading gold nanoparticles. Owing to the mesoporous structure of FDU mesoploymer, it can make gold nanoparticles highly dispersed, and keep a high catalytic activity. Gold nanoparticles catalyst has oxygen as oxidation, which is clean and simple. From the catalytic activity, it is obvious that the catalyst is of good universality, which has a high catalytic activity to aromatic alcohol and heterocyclic alcohol, and certain catalytic activity to fatty alcohols. The experiment results are that the gold nanoparticles catalyst is not very ideal in recycle performance. The next period will concerntrate on the improvement of the catalytic performance and the reducing reasons of the catalytic activity. The preliminary exploration of Ru catalyst is also studied.
