Metal-organic Frameworks As A Precursor For Synthesis Of Cuo/CeO₂Catalysts For Preferential Oxidation Of Co And Au/MOFs Catalysts For Hydrogenation Of P-nitrophenol

Metal-organic frameworks (MOFs), a series of new crystalline and porous solidmaterials constructed from inorganic metal-ion clusters and polytopic organic linkers,are receiving significant attention recently.MOFs possess ultrahigh porosity, largeinternal surface area, adjustable structure, and variability of the functionality ofmetal-ions and organic ligands, thus MOFs show great potential applications in cleanenergy, gas storage and seperation, biomedical imaging, thin film devices, andcatalysis.1. Employing Metal-organic frameworks (MOFs) as precursor, a series ofCuO/CeO2catalysts were synthesized and applied for CO-PROX in H2-rich stream.Compared with A-600catalyst, the B-X samples have been further characterized byXRD, H2-TPR, N2adsorption/desorption, TEM and XPS techniques. The resultsreveal that various MOFs precursors effect significantly on the catalytic activity andthe deactivating of H2O and CO2of CuO/CeO2catalysts.2. Using MOFs as carrier to support gold, and applied to the catalytichydrogenation of p-nitrophenol. The TEM results reveal that MOFs have a greatinfluence on the size of Au.
