DEFect NETwork Materials Science and Engineering Marie Sklodowska-Curie European Training Network (MC-ETN) H2020-MSCA-2014-ITN http://www.defnet-etn.eu/ Hans-Hilmar Mautschke, ITQ-ESR-8 ITQ Valencia, Spain Multifunctional Defect Engineered UiO-type catalysts Metal Organic Frameworks (MOFs) are 3-dimensional network materials build up by inorganic metal clusters interconnected through organic linker molecules. The crystalline structure of those materials gives raise to super high porosity and surface areas, which makes those materials suitable candidates for heterogeneous catalysts. So far MOFs have been applied successfully in different fields like gas sorption/separation, drug delivery and catalysis, even though there are still no industrial relevant applications for these materials. Many attempts have been made to tailor the properties of MOFs to tune catalytic properties, e.g. grafting, postsynthetic modification (PSM) or encapsulation for the creation of coordinatively unsaturated sites (CUS’s), additional functionalities at linker molecules and others. The high variability in pore size and metal centers is superior to related materials like zeolites, where the number of building units is rather limited. MOFs containing hexanuclear ZrO clusters like the ones found in the UiO-66 structure are chemical and thermally quite stable compounds, due to the high coordination number of the zirconium atoms. Defects within the structure have been found as one important feature to enhance catalytic activity and to create Lewis- or Brønsted-acid sites. The aim of this work and DEFect NETwork materials science and engineering project is the synthesis of defective zirconium containing MOFs and their use as heterogeneous acid catalysts in reactions like hydrogen transfer reactions, esterificationor cyclization reactions. Beside Zr other metals (such as Hf, Ce or mixed metal systems) will be introduced. Materials with defective or functionalized linkers will be prepared and evaluated.
