Heteronuclear MOFs for applications in adsorption and redox catalysis

Subject Area Inorganic Molecular Chemistry - Synthesis and Characterisation
Term from 2008 to 2016
Project identifier Deutsche Forschungsgemeinschaft (DFG) - Project number 79644156
 
Aim of this joint project is the rational development of MOF materials for applications in selective adsorption and selective catalysis based on a fundamental understanding of their structure-related functions. Three research groups combine their experience in synthesis/structural analysis, sorption and heterogeneous catalysis to achieve a deeper knowledge on MOF materials with specific functions for technical applications.The investigations focus on porous Cu-MOFs with substituted triazolyl benzoate or isophthalate linkers, developed in the first period of this program. They will be modified in order to adjust the pore geometry and to generate active sites. Size and geometry of the pores and the pore windows will be controlled by linker design (substitution pattern of the triazole and aromatic groups) in order to achieve shape selectivity in adsorption and catalysis, due to differences in shape and size of the adsorptives. Active centres in the MOFs will be generated by introducing a second type of metal ions into the framework. Such heteronuclear MOFs can be synthesized by isomorphous substitution. The resulting selectivity in adsorption and redox catalysis will be studied, e.g., for alkane/alkene separation and alkene oxidation reactions. The correlation of the sorption behavior of the reactants (e.g. CO, O2, hydrocarbons) on MOFs with different linkers and metal sites to their catalytic properties will provide a deeper understanding of the framework-based functions of MOF materials.
