<p class="Haupttext"><span lang="EN-US" style="font-size:6.0pt;line-height:150%"><o:p> </o:p></span></p>
<p class="MsoNormal" style="text-align:justify"><span lang="EN-US" style="font-size:12.0pt;font-family:"Arial","sans-serif"">Metal Organic Frameworks (MOFs) are crystalline organic-inorganic hybrid materials with a regular pore structure similar to zeolites.
Thus, this class of materials possesses potentials as solid catalysts. Compared to solely inorganic zeolite materials new design concepts are possible for metal organic frameworks as catalysts, namely by the inspiration through biocatalysis and/or molecular
catalysis. Thus, together with partners from organic and inorganic chemistry we try to design MOFs which mimic bio or molecular catalysts. In the case of oxidation with molecular oxygen we used particulate methane monooxygenase as inspiration for the design
of appropriate MOF catalysts. In the case of hydrogenation with molecular hydrogen or transfer hydrogenation with isopropanol we used the mechanisms of molecular catalysis (e.g. of Wilkinson catalysts) as inspiration. Catalytic measurements have been performed
and interpreted on the basis of the before mentioned unifying concept between the catalysis disciplines.
<o:p></o:p></span></p>
<p class="MsoNormal" style="text-align:justify"><span lang="EN-US" style="font-size:12.0pt;font-family:"Arial","sans-serif"">Catalytic activities of MOFs in hydrogenation and oxidation have been also demonstrated in literature. However, leaching of metal centers
or reduction of the metal sites to metal nanoparticles have not been considered sufficiently from a chemical engineering point of view. Our work shows that with MOFs the local concentrations at the active sites have to be carefully controlled in order to guarantee
long-term stability of the MOF catalysts. This has consequences also for the reactor design and the operation conditions.
