Gas/Liquid-Phase Catalysis Using MOF-Supported Catalysts
Structural ambiguity of active sites represents a major hurdle for rational catalyst design in heterogeneous catalysis. Using metal–organic frameworks, or MOFs, as the catalyst supports offers a potential solution to this challenge due to their well-defined structures and high crystallinity. Central to our efforts is the use of a zirconium-based MOF featuring a 1,3,6,8-(p-benzoate)pyrene ligand, named NU-1000. Using atomic layer deposition or solvothermal deposition, a wide variety of metal-oxide or -sulfide clusters have been anchored uniformly to the MOF support in large quantity. These clusters can facilitate many shale-gas upgrade processes, including alkane oxidative dehydrogenation, alkene dimerization/oligomerization and selective alkane oxidation to alcohol. Collaborating with other scientists within the Inorganometallic Catalyst Design Center (ICDC) (a Department of Energy-sponsored Energy Frontier Research Center), we aim to elucidate the structure of the active sites of these MOF-supported catalysts using techniques such as synchrotron X-ray absorption and diffraction, microscopic imaging, and computational modeling.
